PCN pre-registration exam, bit by bit.
The Pre-registration Examination for Pharmacists exists to confirm that an intern can practise in Nigeria without endangering the public, and the Pharmacists Council of Nigeria states that purpose plainly. Two things follow from it: the exam is about safe practice rather than academic depth, and with only four attempts permitted, a casual first sitting is an expensive way to find out what is on the paper.

Where pharmacology actually sits in the PCN
An examination whose stated purpose is protecting the public weights pharmacology towards harm. Interactions, contraindications, adverse effects and the drugs with a narrow margin between a dose that works and one that does not are worth more attention than elegant mechanism detail. If you are deciding what to revise next, ask which gap would hurt a patient fastest.
What the PCN publishes about its blueprint
The PCN sets out the examination syllabus in the PEP Manual, which is sold through PCN offices rather than published as a free web document. Anyone quoting exact topic weightings online without reference to that manual is guessing, so buy or borrow a copy rather than planning around a forum post.
Four attempts is the number that should shape your plan
A cap on attempts changes the arithmetic of preparation. Sitting early to see the paper is a strategy that works where resits are unlimited and is reckless where they are not, because each attempt spent scouting is one fewer available when you are genuinely ready. Prepare for the first sitting as though it were the only one.
Build around internship, not against it
Interns revise while working, which rules out long study blocks for most of the year. This is an argument for spaced repetition rather than an obstacle to it: short daily reviews survive a shift pattern in a way that weekend cramming does not, and the drugs you dispensed that day are the ones your memory is most ready to file. Let the work choose the topic and let the review schedule handle retention.
Plan for the data you actually have
Study material that assumes constant connectivity fails at the point of use. Download what you need while you have bandwidth and revise from what is already on the device, so that a lapse in data costs you a convenience rather than a study day. This is a practical constraint worth designing around rather than apologising for.
A study plan shaped by the blueprint
Timings below assume you are revising alongside other commitments rather than full time. Shorten it if you have a clear run at the exam, but keep the order: the slowest skills to build belong at the front, where there is still time for them to settle.
| Months 1-3 | Safety-first pharmacology: interactions, contraindications, narrow margins. |
|---|---|
| Month 4 | Calculations and compounding, drilled to automatic. |
| Month 5 | Law, ethics and practice rules from the PEP Manual. |
| Month 6 | Timed papers, then weak-spot drilling before the March or October sitting. |
Calculations you should be able to do cold
These are the calculation types that turn up most often in PCN questions. Each one opens a free calculator with the formula, a worked example and the mistake that costs most people the mark.
- mg/kg dose calculator — Weight-based dose
- Dilution calculator (C1V1 = C2V2) — Dilution
- Paediatric dose calculator (Clark and Young) — Paediatric dose
- Ratio strength and percentage converter — Ratio strength
The full set lives in the pharmacy calculators hub, and every one of them is free with no sign-up.

Check the official source
Examination formats, eligibility rules and sitting dates change, and this page is a study-planning summary rather than a registration guide. The figures above were taken from material published by the Pharmacists Council of Nigeria (PCN), and you should confirm the current requirements there before you commit to a plan or pay a fee. Our study guide for Nigeria covers what the rest of the pathway looks like.
