Top one percent or Edushastra?

I am a supporter of self-studies for all competitions. But now my performance has hit a plateau. I am scoring well but not moving further than 700 score. Things which worked for me:

Make study groups with your friends

Try to study at the same time each day, and be sure to pace yourself.
Studying every other night for between 45 minutes and two hours will
allow for much more long-term retention of content than weekly
cram-fests and all-nighters.

Learn, Unlearn... & Relearn:

These three words is the best summation of my preparation. Many books & teachers will throw many strategies at you. But the best thing is to keep on practicing till you develop your own strategy and that can only be done when you are unlearning everything you learn and then relearn the same thing.

Get accustomed to the exam:

Try and mimic the actual GMAT as much as you can. Solve the AWA and IR section as well wherever possible. Take the obligatory breaks if you want and eat the same stuff you would eat during the final exam.

Be Flexible with the Test Date:

GMAT is adaptive and we must be adaptive too. Try to reach your optimum and then only decide to go for the test. Everyone will take different time to reach their optimum. I think everyone has a critical peak point they need to exploit. The question is how to identify your optimum. The optimum is when your score will become stagnant even after all practice. When you are sure about your optimum, then choose a suitable date.

Review:

Well here is a little secret. If there is one thing which influences your performance the most it is reviewing. I know so many people who give test after test, solve multiple books for practice but barely spend any time reviewing. Reviewing shows you exactly where you went wrong and helps you overcome those mistakes which you will be most likely to make again. Review every single answer you get wrong.

On timing:

You'll want to spend about 2 minutes per Quant question (perhaps more for Data Sufficiency and less for Problem Solving, although the opposite will be true when you get good at DS) and 2.5 minutes per Integrated Reasoning question. For Verbal, maybe 75 seconds for each Sentence Correction question, <2.5 minutes for Critical Reasoning, 2.5-3.5 minutes for each Reading Comprehension Passage +60-75 seconds each for the questions that follow. The Verbal numbers will vary slightly depending on your strengths and weaknesses, but you have about 1 minute 49 seconds per Verbal question.

Focus on identifying the incorrect Verbal answer choices, not the correct one.

Make sure you can give an explicit reason why you can eliminate every single incorrect answer. If you cannot, you have not mastered that question, as the GMAT frequently has incorrect answer choices that "sound right", and occasionally correct answer choices that "don't sound right".

Books:

For SC & CR, the Manhattan Book is without doubt the best there is. I used a couple of days right at the start of my prep to go through all the rules. I also used Aristotle Prep to supplement my understanding of the rules. According to me, this worked better than simply re-reading the Manhattan Book, as a different approach with varied examples helped drill the rules in my head better. I also completed all questions from OG13 and OG Verbal 16 Guide, and the tougher questions from OG16.

RC needs no books. Practice from all online & offline assets will help.
