Some of the hold up is because a number of guys in the Oct or Nov classes were immediately awarded CA upgrades on 17-05 and 18-01. They made us continue 900 FO training through the LOE. That combined with delays due to sims breaking and just general back log made it so we never went to OE before having to start upgrade training.

My Class date was in Nov, did 900 FO LOE in Late Feb, upgrade class in March, CA LOE about a week ago. Waiting on OE. I never had to repeat anything. All the outliers from the Oct/Nov timeframe have similar timelines.
