Whenever I am reading a paragraph in RC section, I can understand the meaning of each and every word but whenever a difficult paragraph comes, I find it hard to understand what is author trying to tell even if I know the words. I have to go through it for a couple of times to get a good understanding.
Any tips/suggestions to solve this problem would be great.

Try to make a passage map of what you are reading.
For each paragraph, write 10 - 20 words. Write the information provided and the main point of the paragraph.
In this way, you will be able to understand the passage properly.
Also pay attention to the tone of the author. this will help you understand the connotation of the author.
