How to do better on tests?

Question

I’m in my first semester of uni and i’ve just had my first major math exam. i understood the topics, i could do every exercise our professor gave us (most people couldn’t complete them, they’re meant to be really hard), i studied like 2-3 weeks every day for hours. Then the day of the test arrives, and as always i made a lot of stupid mistakes. no mistakes due to a lack of understanding but mistakes i recognized as soon as i walked out. so my question is,  how can i avoid making those mistakes (such as forgetting to write down expressions, forgetting to use absolute values, making mistakes while simplifying,…. etc) even when under pressure and not having enough time? Its definitely not a lack of practice because i worked my bum off for that exam all semester long.

thanks in advance for all answers and please be kind, english is not my native language:)

Answer 1

How long do you have after completing a test, because the simple answer is taking your time reviewing the test after finished. Make sure your sleep is good the night before eat breakfast.

Answer 2

Recreate that same test environment. Set a timer and work through any practice exams released or ones you can find that cover similar content online.

The mental clarity you’re looking for comes from complete understanding of the material, and that comes from practice with the material.
