Chemistry is a core subject for science students writing JAMB UTME, especially those aiming for Medicine, Pharmacy, Engineering, Nursing, and Pure Sciences. Every year, candidates search for the most important JAMB Chemistry topics because JAMB repeats questions from specific areas.
The good news is that JAMB Chemistry is highly predictable. If you focus on the right topics and practice past questions, you can score very high with confidence.
In this article, you’ll discover the most important and frequently tested JAMB Chemistry topics, why they matter, and how to prepare for them effectively.
1. Stoichiometry and Chemical Calculations
This is one of the most important JAMB Chemistry topics and appears every year.
Common Areas Tested:
- Mole concept
- Relative atomic and molecular mass
- Chemical equations
