Some easy steps
These techniques may look overwhelming at first (there are so many of them!) but as you read through you will probably find that you already use some of them.
You don't have to master each one, or even pick one to use overall. You can take a pick-and-mix attitude - some of these will work better in some classes than others - and your classmates may also have suggestions.
Why not have some fun? Get together and see how many silly rhymes or sentences you can make up for one class... it's amazing how well it works!

Rhymes and songs
Once the rhyme is learned, you'll never forget! Everyone remembers the year Colombus discovered America and the order of the alphabet through the rhyme and the song. (And Sesame Street probably has a lot to answer for!)
There are many others, or you can make up your own!
Acronyms
A combination of letters which helps you easily remember a sequence of words For example: 
ROY G. BIV (colors of the visible spectrum)
Red | Orange | Yellow | Green | Blue | Indigo | Violet
PEMDAS (sequence in solving or evaluating math equations)
Parenthesis | Exponents | Multiplication | Division | Addition | Subtraction
IPMAT (stages of cell division)
Interphase | Prophase | Metaphase | Anaphase | Telephase
Acrostics
An invented sentence or poem with a first letter cue For example:
Every Good Boy Deserves Fun
reminds you of the G-clef notes on sheet music: EGBDF
Richard Of York Gave Battle In Vain
gives you the colors of the visible spectrum: Red, Orange, Yellow, Green, Blue, Indigo, Violet
Please Excuse My Dear Aunt Sally
gives you the sequence to solve or evaluate math equations: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
Grouping
Keeping similar ideas together So instead of trying to remember 9 random items, you might only need to remember 3 main groups with 3 items in each group.
For example, if you're trying to remember the main characters in Tolkein's Lord of the Rings, you could try just remembering the list:
Frodo Baggins, Sam Gamgee, Pippin Took, Meriadoc Brandybuck, Gandalf, Boromir, Gimli, Legolas, Aragorn
but it's much easier to remember in groups:
- 4 hobbits - Frodo Baggins, Sam Gamgee, Pippin Took, Meriadoc Brandybuck
- 2 humans - Boromir, Aragorn
- 3 "other" - Gandalf, Gimli, Legolas
