I think the most difficult question on the midterm is the question #5. I am not very familiar with those volume questions at that time. The volume questions could be pretty challenge to us because we need to think out a rotating graph or cut the object into empty cones by ourselves. I realized how to do this kind of question recently.

Tips:

1. More practice, do all the pre-reading questions, all the practice question that teacher gave us, and don’t lose points on the calculation part.
2. Really understand the basic definition of some key words.
