Hello infinityfin,

The first step towards improving your score is to analyze your performance and understand your weak areas. Accuracy or score is often a poor metric and by itself, will not tell you anything.

You need to do the following analysis on the questions you have solved so far. Look at every questions and ask yourself
1. What concept was tested? (In SC, parallelism? comparison?)
2. What question type is it? (In RC, Big Picture type? Anchor-phrase? Inference-based?)
3. If you were between D and E, picked D, and E is the OA - what is the difference between the two? What did you think was wrong with E? What was wrong in D that you missed?
4. What kind of mistake did you make? (Conceptual? Timing? Silly mistake?)

As you do this review, maintain an error log. Read more about the error log here: https://www.crackverbal.com/nailed-it-mi ... crewed-it/
Basically, you would be tagging each question by type, the mistake you made, and the concept tested.

Once you have such a log for 100-200 questions, you can see the patterns in your mistakes - the concepts that trip you up and the type of mistake you are making. Knowing this will help you focus your efforts to fix these gaps and improve your score.

For example, if timing is an issue, you can practice more in test bursts to improve your time management. If certain concepts trip you up, then you need to revisit the fundamentals of those and make sure your understanding it correct.
