How to revise BPT efficiently

I have my BPT sitting in June with a FAR resit and AA. Does anyone have any ideas how to revise BPT efficiently? It takes me 2 hours to go through one question. I got 28 in my second mock down from 38 in my first mock.

I have purchased the ACA Master's revision notes.

Please can someone advise me on more time saving BPT revision techniques?
