Hey! Calm down, you have 10 days more to prepare and be confident for the exam. You can do this by revising topics one by one but don't panic, take it easy. Try solving previous years papers this will help you to know the pattern of questions asked in exam, will also prepare you for the final exam, help you to analyze your weak points/topics on which you can focus more and obviously will help you in time management. As we all know, haste is waste, so try to revise topics very calmly one by one. And if you have prepared any notes Than nothing can be good more than that.

Hope for best.

Thank you
