They do not take away your scratch paper, but if you take the break you need to exit the room and leave your scratch paper behind. Once you are back at the computer, the proctor logs you back in and the clock start ticking.
I suppose if you finish the AWA or Quant sections early you can draw grids.
You are right but this is what I did:
1. Took the 7 minute break
2. I asked the proctor to enter her password and leave the workstation without clicking on OK button. I told her that I want to relax before starting.
3. For next three remaining minutes of break I made the grid and relaxed.
4. When 20 seconds were remaining in teh break, I clicked on OK button and I was on the screen where you read some instructions etc. This screen is timed and will be there for 1 minute. You can also utilize this 1 minute for relaxation.
