Read what you have to learn. Read many times until you understand what it's written there... Concentrate and make connections between all the informations. It's also a good idea to connect with something from the real life (situations, important numbers, and so on). Reorganise everything you learn in a logical way, write somewhere all the important stuff - point out the main ideas - it will be easier for you. Underline every important data, write it in colors, capitals, and so on. Record yourself while you're repeating out loud the things you need to learn, then play the tape over and over again
