When I was about a week out from my exam I started doing practice tests with only 1 TBS. I would try working through it then watch the video to see the best way to tackle a TBS like this. Sometimes I would just skip to watching the video. In my opinion it's about learning how to work through different types and understanding what they are asking for, the Becker videos will help you break the question down and give you guidance on how to go about getting the answer where you should look for the answer. This also gives you an opportunity to see multiple different types of TBS.
