Well, take this time to study whatever materials they gave you. Brush up on your IAP's. Study the 121/135 (whatever you are doing) regs so it makes the regs you learn in indoc easier to undertand. Most importantly...take this next month to RELAX and catch up on your rest! You will be in lock-down for the next month and a half, to two months! You need to be as healthy as possible!
Good luck sir,
