How amazing would it be if you can read 300 times faster then usual. It would save you a lot of time, and you would be able to go over a lot more information in less time then you would normally need.
1. How to focus better
You can easily increase your focus with trackers and pacers. Use a pen or your finger tip to guide your eyes along the lines. This will prevent you from re-reading which makes it faster to go to the next line. Hold your pen flat against your book and underline each line keeping your vision right above the tip of the pen. The pen will serve as a tracker as well as a pacer, maintaining your concentration and speed so you don't get distracted and prevent you from staring.
Don't be concerned about actually understanding what you are reading and make sure you don't take longer than a second for one line.
Repeat this technique while increasing the speed. Maintaining this high speed will help you to get used to it and train your perceptual reflexes. Keep focusing on the exercise and try not to be distracted.
2. Perceptual expansion
This actually means reading 3 words while looking at one word. If you look at the center of the computer screen you will still perceive the sides. Training peripheral vision to register more effectively can increase reading speed by 300%. To give you an idea I use this line; ' I enjoy studying Japanese as much as I enjoy studying Korean.' If you were able to start at 'Japanese' and finish at 'studying' you eliminated 6 of the 11 words, which is more than double the normal speed. This concept is easy to combine with the trackers and pacers from point 1.
I hope this will help you!
