Reddit mentions of Herlitz A6 Ruled Record Card - Assorted Colours (200 Pieces)

Three biggest things in my opinion:

1. Start early.
   
2. Keep notes simple.
   
3. Don't panic.
   
   
4. I'm sure you've heard it from every teacher and every student ever, but it's important. It doesn't have to be often, but make sure you keep on track with work/homework, and revise when you can (for tests etc.). Remember that the more you do now, the less you have to do near the exams.
   
   
5. The biggest problem I found is that I spent way too long making overly detailed notes. I'd recommend buying some revision cards. I bought those ones, and I used them to make notes on. They're good because they can be used in many ways (flashcards, general notes, diagrams) so you can test yourself, but due to their size, you don't over complicate your notes.
   
   
6. Don't panic! People, especially teachers, seem to be good at nothing apart from making you panic (you'll learn this isn't the case one day). You have two whole years yet, just make sure to revise little and often. Even 30 minutes a day at this point is still 30 minutes more than most of the people going into year 10, and you will thank yourself as you get nearer to the exams, trust me. The more you do now, the less you have to do nearer the time, and the less stressed you will be. Remember, it's a couple of months of pain for a lifetime of gain.
