Hey Siddhanth, Congrats on your score buddy!
I am myself taking the Economist GMAT course and recently scored a 710 on one of their diagnostics. The thing that troubled me was that the break up was a 50 Q 39 V. It seems with the same score you have a higher GMAT score.
Did you have a similar experience while studying with them -
1. At the same break up of scores (say x in quant and y in verbal), does the Economist differ from the real GMAT in the overall score it displays?
2. Are real GMAT scores a bit higher than what you usually score on the Economist sample tests?
PS - Would love to hear something other than the +-30 point thing that everybody from Economists seems to be talking about.
