Well I wouldn't recommend getting the Premium (the most $$$) if your writing the exam in June.. only b/c there isn't enough time to cover all the extra's you'd get.. but if your taking the exam in June.. it may be worthwhile....
I'd probably recommend the Essential.. the Exam Disc and Study guides with Practice exam books should be good enough.. if you need some audio pick up the Audio CDs and upload them to your mp3..
Good Luck...
If your willing to spend over a grand for study material... I wouldn't recommend spending it all on Schewser material.. definetly get schewser notes (400$..) and spend the extra on another study provider (Allen, Stalla, anaaystnotes etc)
