Just like to echo michaelf’s advice – ‘practice lots of questions over and over’. It’s the very best thing you can do!
I’ve been finding the ACCASimplified (https://accasimplified.com/) books really helpful. Like michaelf, I bought the BPP text book also and never opened it… reason I’m recommending the ACCASimplified ones are these books just present lots of short-form questions, so I can focus on one topic at a time and rattle out dozens of questions every evening after work rather than do one big one.
