Test taking logic

I usually try to look for another question that gives away the answer to the question I'm stuck on lol

Thats actually the best way to take a test if theres any sort of time limit, go through the whole thing and answer the ones you know or can finish easily, then go back through and answer the ones that will take longer but your sure you can answer, then go back through again and work on all the ones you are completely unsure of. This way if time is running out, you already answered all the ones you know for sure, instead of being halfway done because you sat on one question for way too long. Because you probably got that shit wrong anyway, and now you're blazing through most likely making mistakes just to get some sort of answer on everything before you have to turn it in
