Time estimated studying: Like 4 weeks (and not full time... I work and I have to go to college...). I read the K&B book and solved like 50 mock's questions of several pages. I didn't have a lot of time to study... (my voucher expired today hehe). Also I was reading this page a lot, so I have to thank all of you guys!! Your tips were so useful on the exam! This page is excellent!
