If you find yourself in need of a pusher, use a 3x5 card as a pacer, or use your hand, or your finger. However, there is one caution you should observe if you try this. Be sure that your hand or finger or card is used to push, not merely to follow your eyes. Many people refuse to push themselves faster in reading for fear that they will lose comprehension. However, research shows that there is little relationship between rate and comprehension.
Some students read rapidly and comprehend well, others read slowly and comprehend poorly.
If you can do this, you can also increase your speed. Your concern should be not with how fast you can get through a chapter, but with how quickly you can locate the facts and ideas that you need. This belief is nonsense too, assuming that you have good vision or wear glasses that correct your eye problems. Of course, if you cannot focus your eyes at the reading distance, you will have trouble learning to skim and scan. Furthermore, if you have developed the habit of focusing your eyes too narrowly and looking at word parts, it will be harder for you to learn to sweep down a page of type rapidly.
