You already use a range of reading styles in everyday situations. The normal reading style that you might use for reading a novel is to read in detail, focusing on every word in sequence from start to finish. If it is a magazine you are reading, you might flick through the pages to see which articles are of interest. When you look in a telephone directory for a particular name, you purposefully ignore all other entries and focus your attention on spotting the name you want. These everyday reading skills can be applied to your studies.
To improve your reading skills you need to:
have clear reading goals;
choose the right texts;
use the right reading style;
use note taking techniques.
