My biggest issue is consistently. Every instructor teaches his/her technique. During the 200s you do it one way then learn “my way” or the “line way” in the later lessons. Having had a different instructor for almost every module it gets frustrating. This happened with my last two full courses, then add a non standard pairing with unknown seat fillers and it becomes more challenging because now you have 2 instructors tag teaming you with “technique” at the same time.
The system works though. No extra sims and finished on plan.
