CollegeBoard SAT book

Hello. I recently purchased CollegeBoard’s SAT review book (the big, thick blue one). Inside there are 10 practice tests. I am wondering if the practice tests inside the book are as easy/hard as the actual SAT test? Were your scores similar to the actual SAT test (If you had the book)? If you have any experience or information, please comment below!!!

I am currently in the process of going through the book to prepare for May.

The 10 practice tests are very similar to the real SAT, as they are written by CB themselves. Really, those practice tests and others you can find online are the most accurate practice you can get. The level of difficulty is usually the same (for example math questions always go from easy to hard as you progress through the section.)
