Answer:
Use Khan Academy!
Step-by-step explanation:
I found Khan Academy extremely helpful for preparing for the SAT. You can link your College Board account to a Khan Academy account and Khan Academy will give you practice problems for the specific topics you didn't score as well on. They also allow you to pace out your practice sessions by giving you a daily goal depending on how far away your SAT is. They also have a lot of practice full-length SATs.
