For all the exams you mentioned all you need to do is do past papers you can get your hands on!
I know everyone says this, and I'm sorry I can't be more specific to you, but everyone says it for a reason- because it works.
At GCSE the same questions come up time and time again, so go through mark schemes and learn the model answers. When you finish a paper, mark it yourself and re-do any questions you got wrong. I write the question on one side of a cue card, and the answer on the other. Then I am learning the correct response, and I am creating a future revision tool- very productive haha.
As for controlled assessments and coursework, just listen to your teacher, do all the preparation you can and don't worry too much! You clearly have a good work ethic so that should hold you in good ground.
Good luck with your GCSEs. Hope you get your grades.
