# 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!

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!
