@Acct2374, I can't imagine. I have no clue how people do this exam with family and kids and all that. I admire you.
I would say, examine your approach to studying the MCQs vs TBSs. If you think about it, the TBSs are 50% of your grade, a huge portion, for 3 of the 4 tests (35% for BEC). If you ask me, based on that, preparing for them is AT LEAST as important as preparing for the MCQs. Unlike the MCQs, most TBSs will ask you to sift through gobs of information in a relatively short time, then be able to translate what you find into meaningful answers. And invariably, most of them will be tougher than the ones you practice with any of the software. Being prepared for the form is as important as being ready for the content. It's something you have to practice and be ready for, so that when you're tested on it, you don't crumble under the pressure. The test is designed to beat you down, and you're already tired by the time you get to the TBSs. But they're such a huge chunk of your score, the worst thing you can do is throw up your hands and do a bunch of guessing. Every little bit makes a difference. Don't completely stop doing MCQs, but make sure you dedicate some time for practicing TBSs. Good luck.
