You need to learn to stop comparing yourself to others. Easier said than done, but, you need to realize that everyone is different. I'm still trying to work on this myself because I always see other classmates doing so well and getting high marks and it makes me feel down about myself. But, I have been working on reminding myself that I am different from them and I have my own journey. My classmates are not me and I don't need to be like them. I'm now focusing on myself rather than comparing myself to them. Focus on yourself more and stop worrying about other people. Try mindfulness meditation to help you calm down before and after the test. Try not to pressure yourself too much before the test. Again, easier said than done but it would really help. If it helps, try going to therapy.
Yes. Apply as much as you need. It doesn't matter.
