Answering practise questions

Hi
Just wondered if anyone has similar problems or advice with practise questions. I’ve returned to studying after a very long break (13/14 years!) and am having to refresh my memory on a lot of topics as I work through them. I am going through the lectures/notes plus working through the BPP text book at the same time. After each chapter I am generally comfortable that I understand the majority of the content and try a practice question recommended at the end of the BPP chapter but am mostly completely at a loss of how to answer most of them. They seem so complex compared to what I’ve read in the notes/seen in OT lectures/read in the textbook chapter. Does anyone else find this? Will it get easier as I get further along? Any tips or advice would be very welcome!
