20 Expected Topics And 100 Questions In JAMB Physics 2023

For this sake of my readers writing JAMB Physics, I will share expected topics and questions in JAMB physics 2023.

From my experience as a tutor and lecturer of physics, I know that there are some repeated topics in physics that JAMB can’t do without bringing out questions.

So, if you want to pass physics in JAMB and score above 60, you must master these topics and make sure you solve all possible questions in them.

I know that writing physics in the exam isn’t as easy as other subjects, but early preparation can help you build the muscle to score high in it.
