What is the best SAT prep workbook to use (barrons, kaplan etc.)?

dont listen to go above. They have been working for me. I suggest getting College Board book for actually taking Realistic Practice tests. I think Barrons is really good and also McGraw Hill isnt bad. Basically all the books are good if u use them in the right way. The best way to prepare is to do this however. Takle a full length practice test in real test condidtions. dont give any extra time. then review all wrong answers and see y u got them wrong. Review all math concepts that were realted to the ones u got wrong. Review all grammar rules very carefully. dont waste time on easy math questions. Dont waste rime on sentence coimpletions that are difficult for u. Basically u want to start thinking the way that the test makers think. Thats the best way to prepare IMO.
