Are they all external exams? If you have exams like foreign languages speaking exams which are assessed internally you might be able to ask to move them. I'd suggest checking with your school's exams office asap.
If not, you'll probably just have to plan your revision accordingly. Revise for all exams together, and in between exams prioritise exams happening sooner. Sleep enough so you don't get exhausted and don't let yourself procrastinate or burn out.
Good luck!
