If you're having trouble studying try this useful method and I guarantee you will love it, enjoy, and ace that test!
Acronyms--make up a funny phrase. Every first letter of each word in the phrase should be the beginning of what you have to memorize. For example:

3. Electron Transport
If you needed to memorize "the stages of cellular respiration", make the acronym GCE. Make it funny like:
"Great Cuddly Eskimos" Now isn't that silly and memorable? Put this technique to use in all your subjects in study and sure enough memorizing for that test will be cake...and plenty of fun.
