Also did it last year, got an A band 1. The How To Pass book for higher physics is great, covers about 95% of the essential stuff you need to know - so I'd really recommend it. The questions in the book I didn't really do much of though, but the worked examples and the notes in general were extremely useful to me.
Make sure to do all past papers, specimen and exempler papers. The Hodder Gibson model papers are great too and do them if you can. I think you can find some online for free.
I'd recommend just memorising the answers or process to some of the written questions (as well as understanding it!), as the same ones or similar ones seems to appear year after year. Same with some of the calculations. Examples include explaining how minima are produced, how the question appears and is worded are different but it's ones of those questions that always comes up.
don't ask me about the 2017 open ended question about traffic congestion, that was a joke!
