Study the vocabulary, definitions and know the key concepts.

P.S. Welcome to Fluther.

If it’s multiple choice, eliminate the two obvious wrong answers, then take your best guess from the remaining two.
Also, trust your first gut instinct.

Get a time machine?

But seriously, vocabulary, definitions, and key concepts as @Tropical_Willie suggested.

I’m really not concerned about the test enough to build a time machine, but good suggestion. :]

Thanks for all the thoughts, I will definitely review the vocabulary.

Don’t get distracted.

Relax and have something to eat.

Seriously, it’s too late to add knowledge and trying to cram now is more likely to confuse you than to improve things. If you try you will probably get distracted by thoughts of all the stuff you might not know which can be very demoralising. But your brain needs a ton of glucose to function at its best so have a snack.

Eat, shut your phone off, get off the internet. Use the 2 hours for studying only.

Make a meticulous cheat sheet. (but make sure you do not actually use it in the test).
Because by doing the cheat sheet, you are actually thinking about the subject, hence the learning effect.

so how do you think you did?

I think I did pretty well, thanks guys! :]

Drink heavily…if you’ve a test in two hours and haven’t prepared for it, you’re wasting your time. You need to be as relaxed as possible to do well, and alcohol’s depressive effects will do that for you. Oh, and don’t do anything like that again, silly!

That’s more than enough time.
