I understand that Entity Taxation is the most heavily tested topic for REG, and have seen lots of old comments here saying how important it is to master basis. Is this still the case? I took TCP earlier this year, and basis was prevelant on that exam, but I haven't really been able to find many basis related MCQs/TBS while studying for REG with Becker. Is there anything basis related I would benefit from focusing on mastering before I sit for my exam?
