It is really hard to be patient... I would love to start studying
Think of it this way. Right now you got lots of free time. Accomplish all the things that you could possibly need to do while you're gone at training. Not sure about your family situation but spend as much time with family & friends as you can before you leave.
Also, if you were to study right now, you'd be doing it for free. Once you get to training, you get PAID
to study $$!!
That's how I justified it! Good luck!
