How do you eat an elephant?
One bite at a time!!
Maybe in this case PR isn't what you're looking for and you'd be better off using a 'standard' mnemonic system.
So 1. Look for patterns in the info. 2. Break it down eg just try and learn say the starters for now 3. Use a mnemonic to learn what info you've identified.4. Test yourself!
Check out this for mnemonic systems: http://www.demon.co.uk/mindtool/memory.html
And remember, it is possible or else nobody would be working there!
Good luck!
