About me: I'm a Harvard Grad, SAT/ACT/GRE perfect scorer, and professional SAT test-prep tutor since 2002. Below are my top 11 personal recommendations for SAT prep practice tests, strategy and learning books, online learning programs, videos, and the like:
Unless otherwise noted above, the materials are paid materials. In some cases where I have indicated "free videos," (SuperTutor TV, 1600.io, and SAT Quantum, for example), there are paid video options as well.
DISCLAIMER: In general, I tend to rank videos lower than books, because I find that learning from books and adaptive online learning programs is more effective than learning from static videos.
I would caution against a video-heavy learning approach, which is tempting due to its ease/convenience, but often leads to low retention as a result of passive learning.
