Preliminary Reading and RC
One of the most important aspects of preparing for reading comprehension in the GMAT is preliminary reading – that is, reading to be done before you start tackling GMAT RC passages in order to prepare you for the challenges that those passages will throw up.
One challenge that you will face on Reading Comprehension passages is that they tend to be about unfamiliar topics and concepts; and talk about unfamiliar terms and fields. They use difficult phrasing and vocabulary, and complicated sentence structure. The only way to get used to the level of complexity you will find in GMAT passages is to read widely.
Another challenge is the fact that reading passages on screen means that you may not be able to see the whole passage at a time, and may have to scroll up and down to read the rest of the passage. This is very different from reading on paper, where you can usually see the whole passage on screen at a glance. The fact that you can’t see the whole of the passage at once when you read long passages onscreen, makes comprehending the passage much more difficult.
