How many questions are in JAMB physics?

The JAMB Physics usually consists of 40 questions and are all objectives

Are JAMB questions repeated?

Yes! JAMB usually repeat questions and that’s why students that read JAMB series or Past questions always have advantage over those that don’t.

What will JAMB set in chemistry?

You will have to visit a new page for that question and it is yet to be posted here.
