what study guides/websites do you guys recommend for all the 3 sciences that cover all the portion in the test?
I used Barron’s for chem. Highly recommend. Google SAT chemistry practice test and you should be able to find some. Practice tests are actually the best for learning imo (if you review answer explanations. Also search that on the forum, and you’ll find plenty more advice.
I don’t know if there are any all-in-one study guides, however, if that’s what you are asking.
