I’d say I’m alright at taking tests, the trick is to write down the information you think you’ll forget at the beginning of the test as well as budget your time. Let’s say you have a 20 question test with 35 minutes to complete it, answer the ones you know first, then go back and use process of elimination to complete the rest. Another thing you can do if you’re having trouble concentrating is after every 4 question you complete, give yourself roughly 3 minutes to doodle something quickly. This can help relive your frustration as well as increasing your creativity to help you on the test. I hope that helps!
