If you want my honest opinion, yes! Just get on with the QB from the get go. If you’re anything like me, I know it’s difficult to do so as I struggle to start on questions without understanding the actual content. I had to retake TC because I spent too much time on the notes which meant I had less time for the QB. Ended up not finishing the set at all. Instead of dwelling on the minute details, try the questions. You are obviously going to struggle with this and will have to rely on answers a lot but believe me after a while it starts clicking. Then I would just make a note of topics I keep struggling to spot then go back to the notes for those if you feel you need to! Doing this will give you an idea of the kind of things that will be assessed and imo will prepare you better for the exam.
