Exam solutions will be your lifeline for maths, trust me and do loads of past papers throughout the year.
Idk much about the rest of your subjects but they seem to be v content based, so i suggest you review the content before you start learning it in class, that way you already have some knowledge on it and then when your teacher teaches it to you, you can ask questions about what you dont understand etc, and review your class work every week so it will be stored better in your long term memory.
Also i find mind maps are very helpful for content based subjects, I used them a lot in psychology, it can really help you visualise the information, but thats just me, i'm a very visual learner, you should research what sort of revision tactics work best for you and integrate them into your every day schedule. You should really start to revise as soon as you can, thats one of the many mistakes i made.
