19 Most Repeated Topics in JAMB Biology Exam 2024

The JAMB examination is the most challenging exam for many Nigerian students.

It is a test that determines whether or not you will gain admission to the tertiary institution to study your course and institution of choice.

The common mistake by many students sitting for the JAMB examination is not preparing using the JAMB syllabus for Biology.

You must know that the secret of scoring above 70 in the JAMB Biology exam is to read all the topics in the syllabus and practice past questions.

In this post, you will see the most repeated topics in the JAMB Biology examination.

Let me know in the comment if you have any questions or need further clarification. I will be glad to get back to you as soon as possible.
