I found Sarfraz's methods very logical and easy to apply.  Coming from a Liberal Arts background, I was approaching Quant questions from a very technical mindset which was hampering my time. His common sense approach to questions completely changed how I was tackling the Quant section and played a pivotal role in increasing my score from 675 to 755.

While Sarfraz is great at teaching concepts, what made the biggest difference for me was his understanding of test taking strategy.  Before meeting Sarfraz, my biggest problem had been the inability to deliver on test day while scoring great on the mocks. We spent most of our time together fine tuning my testing strategy - from time management to when to guess to the section order to how to manage anxiety. In the end, it made a massive difference to my performance on test day. 

Sarfraz sir deserves all the credit for taking my DI score to a 90. I had pretty much given up on DI, as the questions looked completely random to me and I couldn't make any sense of where to start. Within just 3 sessions, sir had completely changed the way I was approaching DI. Things began to look a lot more manageable and I felt a lot more in control, especially while answering those crazy MSR questions.  If you are struggling with DI, look no further.

As a native English speaker, it was a little embarrassing to be scoring below 80 on Verbal.  I was also struggling massively with time. I connected with Sarfraz on Reddit and that was the best thing that could happen to my prep. He made a huge contribution to my prep, both from a conceptual and strategy perspective. He also really makes you believe that you can do it, which helps big time on test day.

I remember telling Sarfraz in our first meeting that I absolutely hated Data Insights.  He replied that while he had no intentions of making me love DI, he'd definitely make sure that I excelled in it. It was that practical approach of his that stuck with me - that ability to get the job done without bothering with whether you like a question or not. He almost made me unemotional about the GMAT, which helped a lot in controlling my nerves on test day. The DI 90 was still a surprise (more like a shock), but all credit goes to him.

It was a pleasure studying from Sarfraz. I did the entire 40-hour course with him and found him extremely professional in his approach, be it with regards to time or flexibility. He was always available and willing to help out even with the silliest of questions. It was pretty evident that he was extremely knowledgable about the test and I blindly followed whatever he said. The result was a great score. I strongly recommend him to everyone.
