As I mentioned earlier, V 25 denotes a weaker understanding of basic concepts. Looking at your ESR, I can confidently say that you completed your Verbal section in about 60 minutes. That is Very fast. I scored 38 in V and I had to rush through by the end of the section. This disparity between us is because you could not comprehend the intricacies in the difficult questions, a fact supported by the question difficulty graph. Almost all the questions you got right were of difficulty Low or between Low and Medium. So, here are the steps to improve.
Step 1. Learn the basic concepts in RC, SC, and CR.
Step 2. Practice enough questions applying those concepts
Step 3. Take a mock test to diagnose your weakest area
Step 4. Improve your weakest area
Step 5. Go to Step 3.
Step 6. Take GMAT when you feel you are ready.
