Scored a 740 !

Splits:
740 -> V42,Q48, 5/8 on IR, 5/6 AWA

Profile:
23 year old Indian, Male, Engineer working as an analytics consultant.

Preparation:
Starting out, I took mocks to diagnose where i stood and I was at the ~590-600 level. Joined GMAT classes at Jamboree Chennai (Nungambakkam branch). It was a 3 month program and was very structured, aided with concise material. Did not do a lot of self prep, but diligently attended the classes and was focused during them. 3 Months passed, and I got busy with work (Ideally should've taken a couple mocks and written my GMAT then). A couple of months later, I realized i had my deadlines approaching and so i just booked my exam giving myself a month's time. During this time, I just used the OG for verbal, and Jamboree's material for Quant. Took some mocks and got all kinds of scores from ~650-710. Finally wrote my GMAT (Was super hard ! More than any of my mocks) and got an unexpected 740 ! Was definitely not expecting more than a 700-720, But hey

And looking back, things i think that helped me:
-> Knowing the right approach to SC questions save loads of time in Verbal. A lot of material is out there, but just attending Jamboree (Faculty - Srivatsan) classes was 80% work done (given you have a reasonable foundation in grammar). Also, I feel OG is all you mostly need if you've nailed down the approach, and taken enough timed tests.
-> Approach to data sufficiency questions (Especially inequalities and equations related; I got 6-8 of these in my GMAT). Jamboree (Faculty- JaiGanesh) definitely helped me out here. My Quant score was also not that great, owing to my lack of prep. Quant definitely is a product of time/effort you put in (Unlike verbal where you can plateau easily).
-> Completely relaxed during the exam, zero pressure. Can't stress this enough.
-> I took the GMAT official mocks in the final week. I guess this was the right thing to do, since they are the most accurate predictors IMO.

Thanks for reading !
