Bad grades

[Mao]

I had the same problem too. What I did was I learned to compartmentalise; it helps me concentrate on the exam I'm currently taking and not the previous ones. Memories of tests taken before can affect your performance on the current one you're taking. They can make you either overconfident or depressed depending on its outcome. Try to think that every test is always a fresh start, you should set aside memories of accomplishments and failures.
