Well done, dude... I think that timing is the one area that I have neglected over the years, and it has punished me severely... Specifically quant..
I have found that if you have a difficult time sticking to the 2 min time limit per question during the test, take a MGMAT test, and instead of selecting 75 mins for the entire section, select 120 seconds per question.. This will sort of give you an idea of what it takes to answer each q in the allotted time period. Granted, you will spend a little more or a little less time per question depending on the difficulty, it was truly an eye opener for me. For the longest, I couldnt figure out why I was consistently hitting 570-580 every time in practice, but when i was forced to move on via this method, my quant score surged and put me in the 640-660 range consistently on Manhattan tests. As you practice under these time constraints, you begin to mentally create an internal stopwatch that will give you an idea of timing throughout the section... It is absolutely imperative that you finish strong and are not forced to guess on problems that you can answer under normal conditions. Best guess, and keep it movin'... But i digress... Well done, OP.. I am inspired
