I joined Siddharth over a 30 minutes' call today. First, I must admire his professionalism for being on time and answering all my questions with extreme clarity and unambiguity.
He was able to list down all the resources and even better, discuss his insights from his score reports from scores of 700 and 770, and how I can formulate my strategy on the exam day to cross the 710-720 mark.
As I understood from him, once you cross 680-690, getting to 730+ is not about knowledge but about strategy and execution. I highly recommend learning from Siddharth's experience and insights if you are starting out right now or like me are stuck at around 710 and unable to cross that mark.
