Hey Navlites..I agree with Flyaway, I can take some time, mine took about 3 weeks, but from what Ive heard and red 3-4 weeks is normal. Hang in there and stay positive.
Flyaway, it took over a week before i got an email saying they would call my references and then another week to call my references. It seems to vary, like you found out a few days after, that they were going to call your references. Maybe they are all full for this GS on the 6th and there is no point in calling your references now, when the next ground school might be sometime later.
Stay positive, no news is good news, but agree the waiting is hard, very hard.
