SAT is a standardised test. It is designed in such a way that you can't use the general academical approach to answers the questions. Before answering any of the questions of SAT, try to understand what the Test Writers asking for. Yet being a student, test takers can't understand what to do. In this state, there are some books test takers can follow to boost up the ability to correct as much questions as possible. There are plenty of resources for SAT exams but I have mentioned only few which I got referenced from a lot of people who scored top in SAT.
