You need to find out where you went wrong and fix it and at the same time you need to effectively study your A2. There’s plenty of threads on here about people’s study routines, study tips, etc.
But if you’re dead serious about getting those grades, my number one tip is instead of revising at home and studying in school, study at home and revise in school. Always make sure you’re about a chapter ahead of class and if anything flags up, speak to your teacher in your next lesson and that way you don’t fall behind. You really can’t afford to fall behind because you’re stuck on one thing, it wastes so much time, by working ahead you'll never fall behind and have more time to solidify your knowledge
