Dear Jane,  

Hi! Thank you for your letter. I can say that I`m always nervous before exams. I usually try to get enough sleep before exam. I come in advance in order to avoid panic attacks. I make breathing exercises that help calm me down. As I am not good at Math, so it is the most difficult exam for me. Usually I study rules, do sums and learn as much as possible. I make a study schedule with regular breaks. Sometimes I ask my teacher to explain me unclear tasks. To my mind, the most important thing for preparing is to start early and strictly follow to the study schedule.

Best wishes,

Liz
