Lots of questions-like Chantigian and Hall book (phenomenal) in addition to old ASA written exams. I scored 2.5 SD above the mean on the writtens. Just do lots of questions-you'll be fine-Don't buy into the scare tactics and jedi mindtricks...
Yeah-the ones on the ASA website-even though they are old-they are still fairly useful and applicable to the real thing-plus no K type questions anymore....
