To start, I'd do two things.raunekk wrote:How to increase comprehension with speed and avoid re-reading of lines??
First, read, read some more, and then read some more. The more reading you do, the more comfortable you'll be. You don't need to read actual GMAT materials: read material similar to what you'll see on the GMAT.
For example, read periodicals such as The Economist and National Geographic (great if you have trouble with science passages). For CR practice, read the editorial section of major newspapers (short and opinionated essays). As you read, take notes just as you would on the actual GMAT.
Also, as much as possible do your reading online, since that's what you'll need to do on test day. Reading while looking down requires different "muscles" than reading while looking up at a screen - most people find computer reading much more tiring and have more trouble staying focused.
Second, read critically. A critical reader thinks while reading. A critical reader looks for keywords (e.g. but, therefore, moreover, most importantly...) to help anticipate where an author is going. A critical reader roadmaps the passage on her scratch paper to make it easy to research the answers to questions. A critical reader focuses on the big picture and doesn't dwell on the details.
Good luck!
