Yomi BlackMost candidates who fail Chemistry at this level did the work. They did it on the topics they already understood, and in a format that is marked by machine. There is no method mark, no partial credit and no examiner to persuade that produces nothing.

- Format here
- Computer-based multiple choice only, inside one timed session covering all four subjects together
- Depth
- A ranking depth rather than a teaching depth: breadth across the syllabus, tested fast, with no essay
- What the grade does
- Part of a score out of 400 that orders you against every other candidate for a fixed number of places
- Hardest part
- The mole concept sits underneath most of the calculation marks, and a candidate who has not internalised it loses across the whole paper rather than in one topic.

- Reporting titration values to the wrong number of decimal places.
What you are actually being measured on
The papers are computer-based multiple choice only, inside one timed session covering all four subjects together, and they are marked by machine. There is no method mark, no partial credit and no examiner to persuade. There is no pass. There is a rank, and the only question is whether enough candidates scored below you.
The preparation that fits it: speed and coverage rather than depth. A candidate who knows a topic thoroughly but slowly is at a disadvantage here that would not exist in a written examination.
What people ask about Chemistry
Is Chemistry compulsory?
No. It is a science subject, chosen as one of your electives, and you should choose it because a course you want names it.
What is it required for?
Medicine, pharmacy, chemical engineering, biochemistry, agriculture, nursing and the physical sciences.
How many papers are there?
Objective, essay, and a practical or alternative to practical.
What makes it hard?
The mole concept sits underneath most of the calculation marks, and a candidate who has not internalised it loses across the whole paper rather than in one topic.
What is the most common way candidates lose marks?
Reporting titration values to the wrong number of decimal places.
Where do I get the official syllabus?
From JAMB, on its own site, free. Check the year range on the cover before you use it.
How long do I need?
Six focused weeks will move a grade if the work is aimed at what your diagnostic paper exposed. Six months aimed at topics you already know will not.
Should I get a tutor for this subject?
If your problem is that the topic was never taught, yes, and specifically for those topics. If your problem is presentation or pacing, a tutor helps less than timed practice against the mark scheme.
What makes the subject hard
The mole concept sits underneath most of the calculation marks, and a candidate who has not internalised it loses across the whole paper rather than in one topic.
That changes the plan. A subject that punishes presentation needs practice in presentation. A subject that compounds needs its foundations fixed first. More hours on the wrong layer produce the same result as none.
The three losses to eliminate first
- Reporting titration values to the wrong number of decimal places.
- Balancing equations carelessly, which cascades through every calculation that follows.
- Ignoring the concordant-titres convention in the practical and averaging everything.
Each is worth more than an extra topic learned, because they are losses on material you already know. Fixing a habit converts work you have already done into marks you are currently not getting.
Cover the ground, worst first
- Separation of mixtures and purification.
- Atomic structure and bonding.
- The periodic table and periodicity.
- Stoichiometry and the mole concept.
- States of matter and gas laws.
- Energetics, rates and equilibrium.
- Acids, bases and salts.
- Oxidation and reduction, electrolysis.
- Organic chemistry.
- Metals, non-metals and their compounds.
How to weight your time
Objective, essay, and a practical or alternative to practical.
Split your preparation in roughly that proportion, then adjust towards whichever component your diagnostic exposed.
Do the stoichiometry until it is automatic. Every other calculation topic in the subject stands on it.
A six-week plan
- Week one. A full past paper under time, in this examination’s format. Mark it honestly. Tag every error.
- Week two. The topics your teaching never covered. Highest return per hour.
- Week three. Drill the three losses above until they stop happening.
- Week four. A second full paper. Compare the error pattern with week one.
- Week five. Your weakest component, whether that is the practical, the essay or the objective paper.
- Week six. A third paper, then consolidation. No new material.
What the grade buys you
Here the grade is part of a score out of 400 that orders you against every other candidate for a fixed number of places. Chemistry is required for medicine, pharmacy, chemical engineering, biochemistry, agriculture, nursing and the physical sciences, and it is checked individually at admission. One sitting a year, in a session assigned to you that cannot be changed.
