Sadly, I don't do any of your subjects. However, I am an expert on last-minute cramming. So what I'd advise is to grab a friend and hop on a call with them, then go to a physics and math tutor and find your subject, then go through testing each other on the detailed notes version for all possible topics that could show up. This works because you already have the knowledge stored passively in your long-term memory. So when it's refreshed, you will transfer it to your short-term memory and just make it easier for the exam as you cover all the content and understand all the gaps you forgot, so you can focus slightly more on those to the point they become your expertise . After this, just do a quick run-through of the exam structure, and you should be chilling for an easy A* (which works every time). Also, if your exam board has them look at examiner reports, it just helps give a quick overview of what common misconceptions occur and what the best students do for full marks in more depth than your teachers will go into.
