Has anyone here taken a B737NG systems test?

I’m starting my B737 type rating in two weeks, and I’ve already completed the B737NG CPAT course.

My school mentioned that there will be a systems exam on the first day, but I’m not sure how to prepare for it.

It feels pretty overwhelming to fully understand all the systems and be ready to answer questions right away.

Is there usually a question bank for this kind of test?

Also, is it typically multiple choice (3 or 4 options), and about how many questions are there?

If anyone has experience with this, I’d really appreciate it if you could share!
