Prof. Bu makes only 2/3 midterms count which helps if you messed up on a midterm. They were also on ALEKS which is also the platform where you do your HW on. If you master the ALEKS HW problems then you've practically done the midterm already. Final was on paper but covered similiar concepts covered in ALEKS and in lecture.

Professor reads off of powerpoints, sometimes you understand the material and sometimes you have no idea what she's talking about. She records lectures and doesn't take attendance.

If you don't go to lectures, make sure to go to recitations and focus on the ALEKS homework's.
