SAT Vocabulary Test is based 1200+ basic SAT words. Each test sheet has 12 questions that are produced dynamically.
it has a good interface and although not really mind-crunching words it is quite useful
I actually hated the interface and background. I was expecting it to be like quizlet where you could test yourself AND have flashcards. There are much better apps out there.
