Chemistry for the JAMB Exam — Luzon candidates
10% of the JAMB test plan. Atomic structure, bonding, stoichiometry, organic reactions, and industrial chemistry in JAMB Chemistry. Calibrated for Luzon-based Filipino candidates.
If you have already studied this content from a textbook, you know the material. The question this page answers is whether you can apply it under exam conditions. 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 Luzon candidates preparing for JAMB, the calibration of study to local context matters: Luzon hosts Manila, the dominant Pearson VUE NCLEX site in the Philippines, plus the largest IELTS and TOEFL cohorts. CHED-accredited nursing programs are concentrated in Metro Manila.
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).
- 4For NCLEX-RN: the Pearson VUE Manila centre is the only PH NCLEX site — book 6–8 weeks in advance, especially Q1 (post-graduation surge).
- 5CGFNS CES is mandatory for U.S. board endorsement of Filipino nursing credentials — start the application the same week you confirm your NCLEX ATT.
- 6For IELTS: British Council and IDP both run multiple weekly sessions in Manila. Speaking-test slots in Makati and Pasig fill first; book a Quezon City slot if you can travel.
Sample JAMB Chemistry questions

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.
