I attempt 2 RC but my chances of getting answer correct is low ending up with more negative please help me how to solve this problem

Step 1: Choose what works best for you. (VA or RC)
Step 2: After this, if you choose RC then you have to focus on reading RC carefully (With full focus and take your time, can range from 3 to 6 min depending on your command on language and level of difficulty of the Passage). (Context is understand main points of each paragraph). After this try to focus on getting reason based or direct questions correct and avoid all the inference based/ weaken/ strengthen questions.
Step 3: If you are able to do the above then go 1 level up by adding one more RC to you bucket with same approach and then one more. This must enable you to at least cover 10 correct questions in the worst case.
Consider reading old PYQ RCs to get a grip on language.
For VA practice would help develop the approach.

Hope this helps!!
Best of Luck!!
