Slow at reading?

Imagine that you’re sitting in class and is about to take a literature test. The teacher passes out the test papers and when it gets to you, you started reading and notice that most of the stuff you’re reading doesn't make a single sense to you. You have no idea what it’s about! You keep re-reading the same passage over and over again to no avail. What did you do wrong?

Stop talking to yourself when you read. People talk to themselves in 2 ways, by:
vocalizing, which is the actual moving of your lips as you read, and
sub vocalizing, which is talking to yourself in your head as you silently read.

Don't keep re-reading the same phrases.
Poor readers habitually read and re-read the same phrase over and over again. This habit of making "regressions" doubles or triples reading time and often does not result in better comprehension. A single careful, attentive reading may not be enough for full comprehension, but is often more effective than constant regressions in the middle of a reading. It is best to work on paying closer attention the first time through.

Vary your reading rate to suit the difficulty and type of writing of the text. Poor readers always read at the same slow rate. An efficient reader speeds up for easier material and slows down for the hard. Some things were not meant to be read quickly at all.
