An effective revision schedule is one which is easiest to follow for you and one which you know you will follow. There is no set format. It can be a list in your notepad or it can be made on your laptop. The most effective revision schedule is one where you learn the most. Keep this in mind when creating yours!
Inform your school immediately. Don’t wait until the exam comes to tell them. No matter what the illness is, get a doctor’s note so that you have proof. Depending on the severity of the illness, your school will decide whether you are fit or not to take the exam. Work with your school to ensure that you put yourself in the best position for yourself.
You have to do all practice papers and do all the topic questions. Make a list or highlight the questions that you feel like you keep getting wrong. Take these to your subject teacher and go through where exactly you are struggling. They will be able to help you out and offer support.
