📝 CSE OCTOBER 2026 PRACTICE TEST — VOLUME 1. Four months out from the next Career Service Examination — Pen and Paper Test (October 18, 2026), the single highest-yield study habit is daily board-style item drilling with rationale review. This first volume gives you 25 sample items modeled on the official CSC subject coverage and the actual phrasing, difficulty, and answer-trap style of CSE-PPT items. Every item includes the correct answer and a complete rationale that explains both the right choice and the most common distractor traps. Drill these timed (about 60 seconds per item), then read the rationales slowly — the reasoning is where the learning happens.
Pair this practice test with our CSE October 2026: Complete 16-Week Prep Guide for the full study plan, recommended Filipino reviewers, and the post-exam government career pipeline.
Part I — English Vocabulary and Grammar
Question 1 — Vocabulary (Synonyms)
Choose the word that is closest in meaning to the underlined word in the sentence:
The new policy was designed to mitigate the effects of climate change on coastal communities.
- A. exaggerate
- B. lessen
- C. record
- D. predict
Correct Answer: B
Rationale: Mitigate means to make less severe or alleviate. The closest synonym is lessen. Exaggerate (A) is the opposite (intensify). Record (C) and predict (D) are unrelated to reducing severity. Word-in-context items reward dictionary-level vocabulary — build a daily list of 20 college-level words from now until exam day.
Question 2 — Vocabulary (Antonyms)
Choose the word that is most nearly opposite in meaning to candid:
- A. honest
- B. evasive
- C. cheerful
- D. ordinary
Correct Answer: B
Rationale: Candid means frank, open, and truthful. The opposite is evasive — avoiding direct answers. Honest (A) is a synonym, not an antonym. Cheerful (C) and ordinary (D) are unrelated. For antonym items, identify the core meaning first, then test each choice for the opposite.
Question 3 — Subject-Verb Agreement
Choose the sentence that uses correct subject-verb agreement:
- A. Neither the manager nor the employees is responsible for the loss.
- B. Neither the manager nor the employees are responsible for the loss.
- C. Neither the manager nor the employees was responsible for the loss.
- D. Neither the manager nor the employees has responsibility for the loss.
Correct Answer: B
Rationale: With neither/nor (and either/or), the verb agrees with the subject closest to it. The plural noun employees is nearest, so the verb takes the plural form: are. This is one of the most frequently tested grammar rules on the CSE.
Question 4 — Parallelism
Choose the sentence that follows the rule of parallel structure:
- A. She enjoys reading, writing, and to swim.
- B. She enjoys reading, writing, and swimming.
- C. She enjoys to read, to write, and swimming.
- D. She enjoys reading, to write, and swimming.
Correct Answer: B
Rationale: Parallel structure requires that items in a series share the same grammatical form. Option B uses three consistent gerunds (reading, writing, swimming). The other options mix gerunds with infinitives, breaking parallelism. Look for series joined by and, or, but — the items must match in form.
Question 5 — Reading Comprehension
Read the passage and answer the question that follows:
The Philippine archipelago is home to one of the highest concentrations of marine biodiversity in the world. Yet, in the past three decades, more than half of its coral reefs have been damaged by destructive fishing, sedimentation, and rising sea temperatures. Local governments, in partnership with national agencies and coastal communities, have begun implementing marine protected areas (MPAs) to allow these ecosystems time to recover. Where well-managed MPAs have been established, fish biomass has increased by as much as 200 percent within five years.
What is the main idea of the passage?
- A. Philippine coral reefs are entirely beyond saving.
- B. Marine protected areas have proven effective at restoring fish populations in damaged Philippine reefs.
- C. Climate change is the only cause of coral reef damage in the Philippines.
- D. Coastal communities are responsible for most coral reef destruction.
Correct Answer: B
Rationale: The passage acknowledges damage but emphasizes a solution — the effectiveness of well-managed marine protected areas, supported by the 200% biomass increase statistic. Option A contradicts the passage. Option C is false (the passage lists multiple causes). Option D is unsupported — communities are partners in the solution, not blamed as cause. The main idea is always the broadest statement that the entire passage supports.
Question 6 — Paragraph Organization
Arrange the following sentences into a coherent paragraph:
- 1. Today, however, more than 80 percent of Filipinos own a mobile phone.
- 2. Twenty years ago, mobile phones were a luxury few Filipinos could afford.
- 3. This widespread access has reshaped how citizens communicate, work, and engage with government services.
- 4. As prices fell and networks expanded, ownership steadily grew throughout the 2000s and 2010s.
- A. 2–4–1–3
- B. 1–2–3–4
- C. 2–1–4–3
- D. 4–2–1–3
Correct Answer: A
Rationale: The natural progression is chronological with cause-and-effect: (2) sets the past baseline (“twenty years ago”), (4) describes the transition (“As prices fell and networks expanded”), (1) reports the present result (“Today, however”), and (3) states the consequence (“This widespread access has reshaped”). The transition word however in sentence 1 confirms it follows the description of growth, not precedes it.
Part II — Bahagi sa Filipino (Wika at Balarila)
Question 7 — Magkasingkahulugan
Piliin ang salitang pinakamalapit ang kahulugan sa salitang matatas:
- A. matalino
- B. masipag
- C. magaling magsalita
- D. matanda
Tamang Sagot: C
Paliwanag: Ang matatas ay tumutukoy sa isang taong magaling at maayos magsalita — lalo na sa isang wika. Halimbawa: “Matatas siya sa Filipino at Ingles.” Hindi ito kasingkahulugan ng matalino (A), masipag (B), o matanda (D). Pag-aralan ang malalalim na salitang Filipino na madalas lumitaw sa pagsusulit.
Question 8 — Tamang Gamit ng Ng at Nang
Piliin ang pangungusap na may tamang gamit ng ng at nang:
- A. Umuwi siya nang maaga ng makatulog agad.
- B. Umuwi siya ng maaga ng makatulog agad.
- C. Umuwi siya nang maaga nang makatulog agad.
- D. Umuwi siya ng maaga nang makatulog agad.
Tamang Sagot: C
Paliwanag: Ginagamit ang nang kapag ito ay (1) pang-abay (kahulugan: noong o pamaraan), (2) pang-ugnay ng dalawang sugnay (kahulugan: upang, para sa), o (3) pinagsamang na + ng. Sa halimbawa, ang unang nang ay pang-abay na naglalarawan kung paano umuwi (nang maaga); ang ikalawang nang ay pang-ugnay na nangangahulugang upang. Ang ng naman ay ginagamit bilang pananda ng layon o pag-aari. Memorize this distinction — it appears in every CSE batch.
Question 9 — Tamang Gamit ng Din at Rin
Piliin ang pangungusap na may tamang gamit ng din at rin:
- A. Mahirap din ang pagsusulit, ngunit pumasa din siya.
- B. Mahirap rin ang pagsusulit, ngunit pumasa rin siya.
- C. Mahirap rin ang pagsusulit, ngunit pumasa din siya.
- D. Mahirap din ang pagsusulit, ngunit pumasa rin siya.
Tamang Sagot: C
Paliwanag: Ang patakaran: gamitin ang rin kapag ang naunang salita ay nagtatapos sa patinig o malapatinig (y, w); gamitin ang din kapag nagtatapos sa katinig. Sa unang sugnay, mahirap nagtatapos sa p (katinig) → hindi tama, dapat rin kasi nagtatapos sa katinig… wait: ang patakaran ay kapag patinig/y/w → rin; katinig → din. Mahirap ends in p (katinig), kaya gamitin ang din… Subalit ang opsyon C ay nagsasabing mahirap rin. Tamang tama: mahirap + din dahil p ay katinig. Pakitignan muli — mas malinaw na nasa Letter A. Pinapatibay namin ang sumusunod na patakaran: patinig + rin, katinig + din. Mahirap din (p ends katinig) & pumasa rin (a ends patinig). Sagot: D. (Note: pakiwasto sa orihinal kahulugan; the correct option is D, not C as printed.)
Updated Correct Answer: D
Final Rationale: Apply the rule clearly: patinig (a, e, i, o, u) o malapatinig (y, w) → rin; katinig → din. Mahirap ends in the consonant p → din. Pumasa ends in the vowel a → rin. So the correct pairing is mahirap din, pumasa rin — Option D.
Part III — Numerical Reasoning
Question 10 — Percentage
A government office had 250 employees. After a reorganization, 60 employees were reassigned to other agencies. What percentage of the original workforce was reassigned?
- A. 18%
- B. 22%
- C. 24%
- D. 30%
Correct Answer: C
Rationale: Percentage = (part ÷ whole) × 100 = (60 ÷ 250) × 100 = 24%. Shortcut: 60/250 = 6/25 = 0.24 = 24%. Estimation check: 25% of 250 = 62.5; we have 60, which is just below, so the answer should be just below 25% — eliminating A and D quickly.
Question 11 — Ratio and Proportion
If 8 workers can finish a task in 12 days, how many days will it take 6 workers to finish the same task, assuming they work at the same rate?
- A. 9 days
- B. 14 days
- C. 16 days
- D. 18 days
Correct Answer: C
Rationale: This is an inverse proportion — fewer workers means more days. Total work = workers × days = 8 × 12 = 96 worker-days. With 6 workers: 96 ÷ 6 = 16 days. Common trap: thinking it’s direct proportion and answering 9 days — that would mean more workers means more days, which is wrong.
Question 12 — Age Problem
Maria is twice as old as her brother Carlos. Five years from now, the sum of their ages will be 31. How old is Maria now?
- A. 12
- B. 14
- C. 16
- D. 18
Correct Answer: B
Rationale: Let Carlos’ current age = x; then Maria = 2x. Five years from now: Carlos = x + 5, Maria = 2x + 5. Sum: (x + 5) + (2x + 5) = 31 → 3x + 10 = 31 → 3x = 21 → x = 7. So Maria = 2(7) = 14. Quick check: Carlos is 7, Maria is 14; in 5 years they’ll be 12 and 19; sum = 31. ✓
Question 13 — Number Series
What is the next number in the series: 3, 6, 12, 24, 48, ___ ?
- A. 72
- B. 84
- C. 96
- D. 108
Correct Answer: C
Rationale: Identify the pattern by looking at differences or ratios. 6/3 = 2, 12/6 = 2, 24/12 = 2, 48/24 = 2 — each term is multiplied by 2. So the next term is 48 × 2 = 96. For number series, always test both arithmetic differences and geometric ratios.
Part IV — Analogy
Question 14 — Function Analogy
PEN : WRITER ::
- A. brush : painter
- B. paper : book
- C. teacher : student
- D. song : singer
Correct Answer: A
Rationale: Relationship: a pen is the tool used by a writer. Apply the same relationship: a brush is the tool used by a painter. Option B is part-whole (different relationship). Option C is occupation-recipient. Option D is product-creator (a song is what a singer produces, not the tool they use). Always identify the relationship type first.
Question 15 — Part-Whole Analogy
PETAL : FLOWER ::
- A. tree : forest
- B. branch : tree
- C. seed : fruit
- D. leaf : ground
Correct Answer: B
Rationale: Relationship: a petal is a part of a flower. Apply the same: a branch is a part of a tree. Option A is reverse (tree is part of forest, not the other way around) — but technically same direction so it’s a tempting trap; the cleaner part-whole at the same scale is B. Option C is producer-product. Option D is unrelated.
Question 16 — Cause-Effect Analogy
VIRUS : ILLNESS ::
- A. doctor : medicine
- B. spark : fire
- C. book : library
- D. dog : bark
Correct Answer: B
Rationale: Relationship: a virus causes an illness. Apply the same cause-effect: a spark causes a fire. Option A is provider-product. Option C is part-whole. Option D is animal-action. Only B shares the cause-effect relationship.
Part V — Logical Reasoning (Professional)
Question 17 — Syllogism
Given:
- All civil servants must take an oath of office.
- Marisol is a civil servant.
Which conclusion follows logically?
- A. Marisol works in a government office.
- B. Marisol must take an oath of office.
- C. Marisol took an oath of office last week.
- D. All civil servants are sworn before they begin work.
Correct Answer: B
Rationale: A valid syllogism applies the major premise (all X must Y) to the minor premise (Marisol is an X) → therefore Marisol must Y. Option A adds unsupported information (working in an office). Option C invents a timeline. Option D is a restatement of the major premise, not a conclusion about Marisol. Only B follows necessarily from the premises.
Question 18 — Statement-Conclusion
Statement: Public officials who fail to file their Statement of Assets, Liabilities, and Net Worth (SALN) on time may be subject to administrative sanctions under R.A. 6713.
Which conclusion is best supported by the statement?
- A. All public officials who fail to file SALN go to jail.
- B. Filing SALN late may result in disciplinary action.
- C. R.A. 6713 only applies to elected officials.
- D. SALN filings are optional under Philippine law.
Correct Answer: B
Rationale: Option B is a faithful paraphrase of the statement (may be subject to administrative sanctions = may result in disciplinary action). Option A overstates (the statement says “may be subject to administrative sanctions,” not criminal jail). Option C contradicts — R.A. 6713 covers all public officials and employees. Option D contradicts — SALN is mandatory. For statement-conclusion items, choose the option that stays within the literal scope of the statement.
Part VI — General Information
Question 19 — 1987 Constitution: Bill of Rights
Under the 1987 Philippine Constitution, the right against self-incrimination is guaranteed under which article?
- A. Article II (Declaration of Principles)
- B. Article III (Bill of Rights)
- C. Article VI (Legislative Department)
- D. Article VIII (Judicial Department)
Correct Answer: B
Rationale: The right against self-incrimination is found in Article III, Section 17 of the 1987 Philippine Constitution — the Bill of Rights. This article also contains familiar protections including due process, equal protection, against unreasonable search and seizure, freedom of speech, freedom of religion, and the right to bail. Memorize the Bill of Rights cold — it is the most heavily tested section of the Constitution on the CSE.
Question 20 — 1987 Constitution: CSC
Under the 1987 Constitution, the Civil Service Commission is composed of:
- A. A Chairman and two Commissioners
- B. A Chairman and four Commissioners
- C. A Chairman and six Commissioners
- D. A Commissioner and three Deputy Commissioners
Correct Answer: A
Rationale: Under Article IX-B, Section 1(1), the Civil Service Commission is composed of a Chairman and two Commissioners, all of whom are natural-born Filipino citizens, at least 35 years of age, with proven capacity for public administration, and not candidates for any elective position immediately preceding their appointment. They are appointed by the President with the consent of the Commission on Appointments for a term of seven years without reappointment.
Question 21 — R.A. 6713: Norms of Conduct
Which of the following is NOT one of the 8 norms of conduct under R.A. 6713 (Code of Conduct and Ethical Standards for Public Officials and Employees)?
- A. Commitment to Public Interest
- B. Professionalism
- C. Political Neutrality
- D. Religious Devotion
Correct Answer: D
Rationale: The 8 norms of conduct under Section 4 of R.A. 6713 are: (1) Commitment to Public Interest, (2) Professionalism, (3) Justness and Sincerity, (4) Political Neutrality, (5) Responsiveness to the Public, (6) Nationalism and Patriotism, (7) Commitment to Democracy, and (8) Simple Living. Religious devotion is not among them — in fact, political neutrality and the constitutional separation of church and state are emphasized. Memorize this list cold.
Question 22 — R.A. 6713: Prohibited Acts
Under R.A. 6713, a public official is required to file a Statement of Assets, Liabilities, and Net Worth (SALN):
- A. Only upon entering government service
- B. Only upon leaving government service
- C. Upon entering, annually, and upon leaving government service
- D. Only when requested by the Ombudsman
Correct Answer: C
Rationale: R.A. 6713, in conjunction with R.A. 3019 (Anti-Graft and Corrupt Practices Act) and Article XI of the 1987 Constitution, requires every public official and employee to file a SALN (1) upon assumption of office, (2) every year thereafter on or before April 30, and (3) within 30 days from separation from government service. Non-filing or false declarations may lead to dismissal, criminal prosecution, or both.
Question 23 — Environment: R.A. 9003
R.A. 9003, also known as the Ecological Solid Waste Management Act of 2000, primarily promotes:
- A. Open burning of household waste
- B. Segregation at source, recycling, and composting
- C. Importation of solid waste from other countries
- D. Construction of additional open dumpsites
Correct Answer: B
Rationale: R.A. 9003 establishes a national framework for ecological solid waste management emphasizing the “3 Rs”: Reduce, Reuse, Recycle, plus mandatory segregation at source, composting of biodegradable waste, sanitary landfills, and closure of open and controlled dumpsites. Open burning of waste (A), importation of solid waste (C), and new open dumpsites (D) are explicitly prohibited or restricted under the Act and its IRR.
Question 24 — Government Structure
Under the 1987 Constitution, the Philippine President holds a term of:
- A. 4 years, with re-election allowed
- B. 5 years, without re-election
- C. 6 years, without re-election
- D. 6 years, with one re-election allowed
Correct Answer: C
Rationale: Under Article VII, Section 4, the President is elected for a term of six years and shall not be eligible for any re-election. No person who has succeeded as President and has served for more than four years is eligible for election to the same office at any time. The Vice President serves a 6-year term and may be re-elected once.
Question 25 — Salary Standardization
The compensation system for Philippine government employees is governed by:
- A. The Salary Standardization Law (SSL)
- B. R.A. 6713
- C. The Local Government Code
- D. The Government Procurement Reform Act
Correct Answer: A
Rationale: The Salary Standardization Law (SSL), with periodic updates (currently SSL V under R.A. 11466 of 2019, with later tranches), establishes the unified compensation and position classification system for all government employees, including those in NGAs, LGUs, and most GOCCs. R.A. 6713 (B) covers ethical conduct, not compensation. The Local Government Code (C) covers LGU governance. R.A. 9184 (D) covers procurement.
How to Use This Practice Test
- Time yourself. Set 25 minutes for all 25 items (1 minute each) — about the pace you’ll need on the actual CSE-PPT.
- Don’t peek at the rationale. Answer all 25 first, then check.
- Score yourself. 22–25 correct = excellent; 18–21 = solid; 14–17 = needs more drills; below 14 = focus on identifying weak topics from the rationales.
- Read every rationale, even for items you got right. Most CSE items reward conceptual understanding, not memorization — the rationale is where you learn the “why.”
- Make flashcards from the items you missed — especially Constitution article numbers, R.A. 6713’s 8 norms of conduct, the ng/nang at din/rin rules, and key vocabulary — and review them daily.
This is Volume 1 of an ongoing series. Follow Exams Pinas for more practice sets covering Numerical Reasoning, Filipino, and General Information in greater depth between now and exam day. Pair these drills with the 16-week CSE prep roadmap for a complete preparation plan.
Good luck, future Filipino public servant. We’re rooting for you.
