It is safe to say that almost anyone can double his or her speed of reading while maintaining equal or even better comprehension. In other words, you can improve the speed with which you get what you want from your reading.
The average college student reads between 250 and 350 words per minute on fiction and non-technical materials. A "good" reading speed is around 500 to 700 words per minute, but some people can read 1000 words per minute or more on these materials.
