Strategy for study as i scheduled my paper on 7 sept.

You should review the questions that you previously attempted 1 month ago. Whatever percentage you get correct now should be much higher than the percentage you got correct 1 month ago. If not, then there is a problem with your retention.

Go through sets of questions - beginning with your weakest section and see how you do. Make sure you keep track of questions you get right/wrong. One option is to create a free account on the Practice Pill Platform and it will automatically track which questions you attempted, which ones you got right/wrong - so you can revisit them later.

Here are some SC practice sets: https://www.gmatpill.com/gmat-practice-t ... -questions

This is crucial for making incremental improvements.

You still have time. I'd save the last 2 weeks for full length practice CATS and mental preparation. For now, focus on fundamentals and test strategy.

First of all. Take a mock test to see where you are!

Then, try solving the question topic by topic starting with easy difficulty and moving forward to medium and hard.

Prepare a xls sheet (topic by topic).. and keep a track of your progress on a daily basis. Use color coding (Red,Orange,Green).
Red: You are weak in theory - brush up your concepts.
Orange - Done with theory but weak in application of the concepts
Green - Done with the topic

Go back to the theory for those topics which are in red. And then move them to orange when you are done with them and then to green when you are done with the practice too!

Hope it helps!
