what to focus on?

I would recommend that you do a past paper, from physic and maths tutor.com, under timed conditions. After that, you should identify which topics you are weakest on.

Once you find the topic, do more questions on this topic: either use past papers by topic that you can find on physics and maths tutor, or use your text book to do more questions.

Repeat with another past paper, up until you can get a satisfactory grade.

No where in your original post does it say this.

I need to raise my grade so I can do a level math but I got a 5.
What would you say are the most common topics that come up in the exam papers.I will be going over all content but want to know what the key topics to perfect are.
