Tax forms are important but I wouldn't say they are more important than knowing basic fundamentals being tested on, such as differences between above-the-line and below-the-line deductions, pass-through basis, due-dates (with and without extension), and estimated payments. I wouldn't go too far to memorize every possible form just the simple ones.
Thanks a lot jd! I worry about the simulation because AICPA likes to give a lot of information that is irrelevant and when I am not familiar with the different types of documentation, I spend a lot of time trying to figure out what is relevant and what is not .. I had really bad experience with simulations from FAR, AUD and BEC.
