Hi I am continuously giving sectionals, taking tests from study room and giving mocks. Also i read book, articles everyday. But my score in english is not improving. Can someone suggest something here

It will take time to improve ur score when u are solving a RC only reading will not help u have to understand the passage theme of the passage and while marking the and u have to eliminate few options to reach to final answer. check out the elimination strategy video in cracku. follow elimination strategy while solving rc hope it will help. try to solve para jumbles and odd one out, gradually ur score will improve.
hope this will help.
