It is so nice to hear it from a Mexican, that whatever conditions people in Mexico City subject themselves to is simply NOT NORMAL! Thank you for verifying my suspicion, which sometimes I tend to second guess... Now you will probably understand why I generally wear dark sunglasses and big massive headphones when I leave the house, even if it's cloudy and my battery is dead.
BTW, are you still up for connecting on discord (or wherever)? Of course only once you've successfully finished your GMAT, for which I still have my fingers crossed...
