Jang v. Chung for SAT Math prep book

I see in the pinned thread that quite a few students are either recommending Dr. Jang or Dr. John Chung’s SAT math prep books. I’m scoring around 600 on my SAT math practice tests, and I want to score higher (potentially around 800). I’m planning on taking the SAT in December. Which one of these books can I buy so I can use over Thanksgiving? Obviously I won’t finish either book, but which one is better for somebody whose strongest point is not math?

Mostly looking for prep books that have a lot of practice tests (I believe Chung’s has 10 practice tests)
