I like using flashcards, start by memorizing groups of 5 and then increase the amount ( while still keeping those you have memorized) till you can go through the whole set. You can reward yourself with a snack every 20 cards you memorize to keep you motivated and energized, Another method I like (this is more like an add on to the flashcards or reading though) is recording yourself saying the information on your phone and listening to it throughout the day, I find that saying the information with a little rhythm to it helps as well.
