Chemistry for the JAMB Exam — Visayas candidates

10% of the JAMB test plan. Atomic structure, bonding, stoichiometry, organic reactions, and industrial chemistry in JAMB Chemistry. Calibrated for Visayan Filipino candidates.

Most exam coaching covers the curriculum at the same depth across all topics. That misses the asymmetry of high-stakes testing: a few topics carry disproportionate weight on the score. Chemistry sits at roughly 10% of the Joint Admissions and Matriculation Board (UTME) content distribution — JAMB Chemistry is required for medicine, pharmacy, engineering, and science admissions. The examination tests conceptual understanding and calculations including mole calculations, stoichiometry, gas laws, and electrochemistry. Organic chemistry (functional groups, reactions, IUPAC naming) carries significant marks. Pass rates for the JAMB are published annually by the awarding body and vary by cohort and locale. For Visayas candidates preparing for JAMB, the calibration of study to local context matters: Cebu City is the second-largest test-taker hub in the Philippines for NCLEX, IELTS, and TOEFL. Visayas-based nurses commonly sit NCLEX in Cebu before applying for U.S. work visas.

Pass rates for JAMB (Visayas, Philippines) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Confusing the IUPAC names of organic functional groups — especially carboxylic acids vs esters
  • !Mole calculation errors — forgetting to divide by molar mass when converting grams to moles
  • !Misidentifying oxidation and reduction in redox reactions

Study tips

  • 1Memorize molar masses of the first 20 elements and common compounds (H₂O, CO₂, HCl, NaOH, H₂SO₄).
  • 2Practice the three-step mole calculation: (1) write balanced equation, (2) find mole ratios, (3) convert units.
  • 3Learn to identify functional groups from structural formulas: -OH (alcohol), -COOH (acid), -COO- (ester), -NH₂ (amine), -CHO (aldehyde).
  • 4NCLEX-RN must currently be taken in Manila — there is no Pearson VUE NCLEX site in the Visayas. Budget Manila travel and accommodation when planning your test date.
  • 5IELTS is available in Cebu at British Council and IDP centres; Cebu speaking-test slots are typically less booked than Manila and quicker to schedule.
  • 6For nursing English-language preparation: PRC (Professional Regulation Commission) cebu hosts review centres that align both NCLEX and IELTS preparation tracks.

Sample JAMB Chemistry questions

These sample items mirror the format and difficulty of real JAMB questions. Practice with thousands more on the free Koydo question bank.

  1. 1

    How many moles of oxygen are needed to completely combust 2 moles of ethane (C₂H₆)?

    • A3
    • B5
    • C7Correct
    • D14
    Why this answer?

    Balanced equation: 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O. The mole ratio C₂H₆ : O₂ = 2 : 7. For 2 moles of ethane, 7 moles of O₂ are required.

Frequently asked questions

Can a calculator be used in JAMB Chemistry?
JAMB UTME does not allow external calculators. The CBT software provides a basic on-screen calculator for numerical questions. Candidates should practice mental arithmetic for mole calculations and gas law problems.
What is the JAMB pass rate for Visayan Filipino candidates?
Pass rates for JAMB candidates in Visayas, Philippines are published periodically by the awarding body. Practice questions, full-length simulations, and weak-area drills are the highest-impact way to improve your odds.
How long should Visayan Filipino candidates study Chemistry for the JAMB?
For most candidates, focused mastery of Chemistry requires 20–40 hours of deliberate practice — drilling sample questions, reviewing failure modes, and timing yourself against exam conditions. Cebu City is the second-largest test-taker hub in the Philippines for NCLEX, IELTS, and TOEFL. Visayas-based nurses commonly sit NCLEX in Cebu before applying for U.S. work visas. Combine Chemistry study with full-length mock exams in the final two weeks before your test date.
