The 2023 JAMB mock exam seems to have gone relatively well going by the updates we received so far on the JAMB 2023 Mock Exam Live Updates thread. Following demands from candidates who did not participate in the JAMB mock exam, we are creating this post to capture some of the questions that were asked in the mock exam. We believe this will help in revision for candidates who did not take the mock, as well as those who took the mock.

The purpose is to give candidates fresh ideas on the kind of questions to expect during the main exam and motivate them towards stepping up their preparation for the main exam that begins on April 29th, 2023. This should not stop candidates from reading their books and practising JAMB Past questions using the 2023 CBT Mobile App and the 2023 CBT Computer Software. 

Questions from JAMB UTME candidates:

Biology
1- in which organism is the flame cell found?
