#1 Blue n' Yellow
I don't know about you, but for me whenever I try to memorize something, I get yellow pad and write with blue ink on it. I actually end up with good results most of the time.
#2 Easy Ones Come First!
When I have LOADS of things to do, I actually do the one I like the most because it motivates me to do more.
If I have lots of time on my hands and there's not much work to do, I usually find myself ending up drawing random typographies and doodles on my notes just because it motivates me. Also, it makes studying fun! Adding a little color won't hurt! ;-)
#4 Manage Your Time Well
This is probably the most important tip out of the five. Well aside from studying, I'm sure you also have other priorities. You could always set your alarm on your phone. A number of minutes/hours for each matter, depending on how much you need to work on it.
#5 Keep Away All Distractions
This is honestly the HARDEST one for me. I am basically attached to my phone. But then, whenever I have to review, I put it in some kind of cabinet.
