Reading Comprehension (RC, as it is normally called) is the most peculiar section in almost all scholastic, entrance and employment tests. The skills in RC make a lot of difference to one’s chances of good grades/selection. Most students find it difficult to tackle topics that are diverse from the field they are in or they are comfortable with. So one needs to develop a taste for even the most obscure and boring topic on this planet. For success in RC one should be able to understand and succeed if one implements the strategies.
Broadly speaking, RC passages can be classified in a few categories. Fact based RC is the simplest form of RC. These types of passages have lot of information in the form of names, numbers etc.
Just make yourself familiar with the structure of the passage. Just see in which paragraph author is talking about what, Mark it. Then when you go to the questions, identify in which paragraph information regarding that question is mentioned. Go to that paragraphand mark the answer.
Inference based RC is the toughest form of RC. This includes passages on topics like Religion, Spirituality, Philosophy, etc. The reading speed is fairly slow in this type of passages. The way to master this type of passages is to read them again and again while practising.
Topic based RC includes passages on any particular topic like economics, astrology, medical science, etc. Generally what makes -these passages tough is usage of technical terms. For success in this type of passages we need to have a fan-understanding of the definition of the term if it is defined in the passage. Read that definition twice if you need to. But don’t worry about technical terms if they are not defined in the passage. Assume them to be non-existent and proceed.
Reading passage first and then questions is the most popular strategy for RC. While answering the question you may come back to the passage to find answer as you have just read the passage initially and not crammed it. But you should not come back for each and every question. The key to success for this strategy is that you should understand the passage very well. We will suggest students to follow this technique from the beginning and work upon this.
Reading questions first and then passage is the strategy followed by a few students. The objective is that after seeing the questions when you read the passage then you read only that part carefully where the answer is given. The flaw with this is that you will not be able to remember all the questions. Besides this, this strategy fails when there are questions that require understanding of the passage.
