I got the “the official sat subject test study guide for math level 2” by college board. I scored higher on those tests than the Barons (even after adding 100 points to my barons score). If anyone has used this book and taken the test, how did it compare? Aiming for an 800.
Heard many recommend Barons in addition to CB book. They said 740 in Barons can bring you 800 in real test. Not absolute but good indicator. You still need to bring your A game to real time test.
