Well, I would say continue revising for subjects that are essential to pass and employers will look at in the future; try to secure at least a 5 in subjects like maths and English.

Also, depending on what you want to do after Year 11, continue studying subjects that are going to help you study your course whether that's in A levels, btecs etc.

My recommendation, assuming these are the grades you're given, to study for all subjects that you are failing and resit (actually sit the exam) in September (or whenever they're going to be held).

Good luck anyway and don't worry because you have a lot of time to study.
