I have my GRE in 2 days. Anything I should keep in mind?
I know I’m supposed to carry my ID (Passport) and maybe the application card/printout.
Can I also carry a water bottle? What arrangements are there if I get thirsty and does it lead to wasted time?
Between sections, do I get v short breaks or does the clock not stop?

URGENT:
I’m posting this on the 26th, with the application deadline being on the 30th. Any suggestions/advice about how to proceed with my Motivation Letter would be big help.
Are they looking for anything specific? Are there points I should definitely include?
Thanks in advance!
