Markguy dont worry your good to go the only reason you havent got called is because the sept 17 class was full and your drug test didnt come in ontime for them to sched a medical.. the next class is 2 weeks from today which is oct 1 but its not a gauranteed date yet they usually make it official about a week and days before the date of the class.. when the make the oct 1 date official you will get an email or call to go for medical and that same day they will give you your class date.. dont worry your good to go.
