Great for SDSU students
If you're a student of SDSU then you probably already know about A Plus Review. A program that's not affiliated with the college that you sign up and pay to go to. Most of the instructors are former students of different teachers at SDSU and they help you study for the exams. You need to check and see if your particular math class and professor is part of the program. Unfortunately not all classes are available at A Plus.
Definitely a program to use to help boost your grade. A bit pricey but worth it.
