I did mine in Addison. To complete the 10 day IFR course I was told to have my written out of the way before I started...So I did. I traveled to Addison and did it to get away from my daily life. It was the roughest 10 days of my life as well! At day 3 I was wondering what in the heck I was doing and contemplated dropping out. However day 5 it started to click and all was right with the world. It was hard but if I can do it anybody can. Just know going in your going to get ALOT of information crammed in your face in short order.
Days where long, we did academics and sims from 8 to noon, break for lunch, 1 to 5 we flew and debriefed. Then I had about 3 hours of homework to do every night. But after 10 days it was over, don't go back to work on day 11, just relax. Not going to lie it was hard for me but worth every ounce of effort that was demanded of me. After I was finished and got back home I went out a few times with my Local CFI to concrete everything in.
I used my post 9/11 bill as well. So be prepared to be able to pay up front the cost of training. The VA will pay you back once you pass. Good luck, its really not all that bad as long as you know you want it. Good luck!
