So I have done some moderate vocab prep but how much attention, according to you, is necessary on vocab if I’m able to answer most SCs in all the blue book and QAS tests I’ve taken so far? I fear that I’m able to answer the q’s in these tests because the lists that I have studied have been compiled using these tests and thus I might not be able to answer in the real test. Is this so?
Depends on your goals. If you won’t be happy with anything less than an 800, then you’ll need to devote a great deal of time to vocab. If you’re OK missing a few sentence comps, then light prep with the most common words is usually sufficient.
The SAT repeats words fairly often, so it’s not necessarily bad that you’ve been learning words based on published SAT history. It might be true, though, that the real thing will have a few more unfamiliar words than the Blue Book if the prep you’ve been doing is all compiled from the Blue Book.
