Can 92A3O ALC phases be done out of sequence? Phase 2 prior to 1?

I was enrolled in phase 1 and 2 of 92A3O ALC at FT Lee and was wait listed for phase 1 but reserved seat for phase 2. Was told for several months I was a go until the other night I was told they are canceling it because didn't have phase 1. I was supposed to start phase 2 next week. I have read it could be done out of sequence. It's it true you can or is it you cannot?
