I did Taus starting in January (step1 end of May). If you didn't have to study for classes you could prob do it in 8-10 weeks easy. I don't like studying alot at once, so I had to start early, but i didn't get serious about it til 4-5 weeks before. I personally suggest it if your willing to put in the time. I got 258 and would call myself an average student. I was typically always the mean on exams.
