Hey, I get that you're nervous because of your past record but remember, this is just the pre boards. Right now is the time to practice, spot your mistakes, and then correct them. Just tell yourself that you will do your best but your actions won't have any long term consequences, it will help you calm down.

It doesn't matter what you did in 11th, all that matter is if youve worked hard this year. So focus on preparing for what is to come.

Hey.you have one day left to prepare yourself. Try to make a plan which will help you overcome the fear and to help you succeed. The idea is that you are in school, so it means you are able to do it. Also it is about the effort. No one told you that is not about being slow or not, but how much effort you put into it. So, make a plan. Do summary of the things you need to know. Write down important things. Repeat out loud the things you need to know for the test. Go for a walk as well. Use the energy that you have to prepare for the test. You can do it. Good luck!
