Important Tips
Use your scrap paper. Since these passages can be long and present difficult sentence and paragraph structures, you may want to use your scrap paper to take brief notes. You can note down the main ideas of each paragraph.
It is particularly useful for remembering where to find factual information. For example, paragraph 1 – types of bacterial diseases. Paragraph 2 – cause of harmonical disorder and likewise.
Quickly read the questions before the passage. This will give you a better idea of what you should be focusing on as you read, in order to answer the questions. Also this will help you in identifying the types of questions and passage.
While answering a factual question, read the passage providing the data very carefully. Also read few lines before that passage. This will save you from the misleading answers.
Tackle the questions with multiple options very carefully. For example, you will see the questions with following choices in the examination -
a. I only
b. III only
c. I and II only
d. I, II and III only
There might be a catch here. You will find I and II in the passage and which are very close to each other. But take out few minutes, read the passage carefully. You may find III as well mentioned in the deeper text. You should review and consider each fact on its own merits.
Lastly and most importantly – Practice will make you perfect. More the number of passages you will tackle, more the skill will get developed.
