everyone say his way to study vocab !!!
During practice tests there are some words that tend to repeat at least once, study them and pay close attention. Get some sat flashcards or just google common sat words. Some may advice to read articles on newspapers (good newspapers) that may actually help you out too.
Quizlet.
@marvin100 I was just reading your examples. For essay in an other post,how do you memorize all of them $-)
Those are jokes 
You really should have a batch of examples that fit all the prompt categories. I find that for most kids, 3-4 great examples are enough for 90% of the prompts and that 8-10 well-chosen examples are enough to fit literally anything CB can throw at you.
@marvin100 i usually use thomas edison , henry ford , and Animal Farm ! What dou you suggest more but just 2 or 3 ! And how i should study them!
