We're memorising 10 core studies of psychology, and all the details about them. Asch, Milgram, Buss, Rosenhan etc., and we have to memorise the context & aims, the procedures & participants, the findings & conclusions, the methodology evaluation and alternative evidence for each.
It might help to put all the numbers you need to memorize into a table (with two columns: descriptions on the left and numbers on the right), memorize the table, and then the first thing you do when taking the exam is write the table from memory.
Here's a way to memorize the table: first make the table, then cover it up so you can't see it, wait 20 seconds, then write as much of it as you can from memory. Study the table again (or even write it again, not from memory), cover it up, wait 20 seconds, then write as much of it as you can from memory. Keep repeating this until you've got it memorized. Waiting 20 seconds is to clear your short term memory. If it's in short term memory when you try to recall it, you can't be sure that it's in long term memory, where you want it.
You can also practice making the motion of typing numbers you want to remember on a numeric keypad. Doing this puts that information in motor memory. I guess it's backup motor memory, since there's some motor memory in the process of writing the numbers with a pen too.
Hopefully my methods aren't
too flawed. It's already tomorrow, so there may not be enough time to get all the numbers in. Anyway, good luck on the exam!
