Tips when answering math tests (FNDMATH) - how to avoid mental block?

Hello! I’m currently taking fndmath. I know how to solve naman, and I constantly answer practice problems. I know the process of each equation and what to do. I also practice questions OUTSIDE of the given examples/practice sets. However, when I am actually taking my tests/LQs ay usually nag memental block ako. As in, even basic questions hindi ko na masagot. How do I overcome this??

Also, do you guys have other tips when taking math tests?
