Learning How to Learn: Powerful Mental Tools to Help You Master Tough Subjects is an excellent free course on Coursera.org that shows very useful techniques on how to learn more, faster.
The course is full of ideas based on actual research (instead of guesswork, which unfortunately is way too common in education) on the best ways to study and learn.
It covers many areas, including the most effective ways to study and retain material in many areas, avoinding procrastination, improving your memory and more.
I spent about 8 hours with the course, including some of the supplementary readings.
Overall, strongly recommended, and full of valuable tips you can use your whole life.
