As I have been preparing for my upcoming exam in December for the last 3 months, I believe that I have some valuable tips for RCs. Here are my strategies to tackle RC questions -
1) Categorize the type of questions you will see into 4 main types- main idea question, supporting idea questions, inference questions and logical structure questions As soon as you read a question, categorize it. This increases your chances of getting it right because you know HOW to answer it. It will also save you time. (refer to OG answers)
2) MAKE USE OF THE LINE REFERENCES - this is a big bonus that the testakers give you. Especially for supporting idea questions, when you refer back to the questions, remmber about the line number.
3) Read the first question first (benifits have been suggested by earlier participants)
4) Be passionate about reading the passages! (benefits also mentioned earlier)
