Have no idea how I got a 99! That is amazing, so pumped up. I feel like a got a few wrong, so they must have been pre-tested questions. First off, I have four tax seasons under my belt and been working in tax for four years, so that definitely was a big advantage. I used Roger and watch all of his lectures, most of them twice. Then I read and reviewed his book probably twice. Also, I took about 1,400 MPQ and maybe 30 TBS practice questions. As a secondary review, I skimmed through the very detailed Surgent books which are very detailed and picked up some good tidbits that helped. I would definitely focus the majority of my time studying on all of the tax portion, that will come in handy the most with the TBS. Also, for the research question I would definitely take some time reviewing the structure of the IRC to help you navigate. Also, keep in mind that the IRC is available to help you with your MPQ and TBS as well and not just for the research question. Good luck and on to Audit!
