WOW CONGRATS
Your post motivated me

Can you share the list of RIGHT FOOD to eat during the breaks?
Did you have any specific routine while taking the tests?
I took GMAT Prep Exam 1(Free) yesterday and scored 720(Q48,V40,IR7), and I have given 3 Optimus Prep mocks before.
1] My brain gets totally exhausted during the test so much so that I am not able to give my 100% during the test. It affects my verbal score.
What should I do?
2] After scoring 720, I have no idea how to improve my quant score. I have gone through
Manhattan Prep Books, whole Optimus Prep on-demand course, OG 2016 2/3 PS and 1/2 of DS done. I am now thinking of studying Veritas Prep Books as their sentence correction book has helped me a lot.
Could you just briefly advise me on how to study further? My dream score is 750
