Hi @"Molly Nelson" I might be wrong but I think for the CAS report to be complete and sent to the school, the letter of recommendation among everything else has to be finalized.
I agree with the above. At the end of the day, your number is your number and that's what they report for rankings, but between two 3.25s the one with the upward trend is better than one who flatlined
Most people report (my own x3 test testing experiences included) being allowed to place their watches on the desk. I do not believe any instructions / guidance provided by LSAC expressly prohibits the practice.
