Answer 1

How could someone possibly tell you what you need to know?

Look at the chapters in the book the test will cover.
Make an outline of the topics in those chapters.
Refer back to your notes to see what the teacher emphasized.
Consider what your other assignments covered for these chapters.

That's what you need to know.
