Teaching yourself to read faster is one of the easiest that you can do to improve yourself. It doesn't require tests, exams, courses or anything other than you doing a few simple things that take minutes to implement and have benefits that will last a life time.
All that you have to do is make a few changes to your reading style. These changes are so small but so instantly rewarding that you'll wonder why you haven't been doing them since you first learned to read.
