# Jamb Physics Past question

Hello Friend! Are you preparing for the Joint Admissions and Matriculations Board JAMB UTME 2023/2024? If yes, then this is for you! Prepare yourself by treating JAMB Physics Past Questions!

I have prepared a series of JAMB Physics Past Questions from 1988 to 2022 which was prepared with the sole purpose of help you prepare very well for the 2023/2024 JAMB!

This JAMB Physics Past Questions comprise of questions, answers and explanation to the answers. Also, you get to discuss! If you feel one answer is not correct, don’t hesitate to leave a comment.

So, take out your pen and a book and start writing!

I must tell that before you start treating past this physics Past Questions, you must have finished reading a physics textbook! At the very least, once!

My friend, here is an opportunity for you to score high in JAMB and to score high, you will need each Mark!
