Here are a few things that seem to work well for me whenever I have a test, or many (in this case), coming up..
- Exercise, even if it's just going for a walk, fresh air always helps clear the mind and get you re-focused.
- Allow yourself breaks, even if it's just lying down and resting for 5 minutes.
- Try not to study for more than 1-2 hours straight, trying to cram in too much information at once never seems to work so well.
- Make sure you get enough sleep because it is important to do this if you want to retain all the information you're trying to learn and stay focused.
- Drink plenty of tea. I don't know what it is about tea, but it always helps me to calm down and gives me new-found energy.
- Always repeat/rehearse the information you're trying to store in your brain, because according to the multi-store model of memory (Atkinson and Shiffrin, 1968) rehearsal ensures the transfer of information from short-term memory to long-term memory.
- Use a number of different methods to gain information, if you're tired of constantly writing, try reading, if you get sick of that, search for a video on youtube related to the area of study you are focusing on.
- Listen to music you enjoy; it could possibly bring about short-term improvement of particular memory tasks (such as remembering information) (The Mozart Effect).
- Discuss what you're learnt with anyone willing to listen; verbally repeating information you have learnt helps you to remember it (and teaches the listner something new).
- Don't stress; if you work yourself up over a test, you'll concentrate more on the upcoming stressful situation than the information you actually need to know.
There are plenty more things you can do to help yourself succeed, but this is what I've come up with for now. The only other thing I can say is, if you're in a similar situation like me with exams coming up, good luck!
