The communication exercise for me was on zoom, and they just played a video and we had like 10 minutes to answer a couple questions (written assignment), and then we were put in breakout rooms and each person answered 1 question (interview-style). Also, just because you get invited to the communication exercise doesn't mean you're accepted, but you are definitely steps closer to being admitted.
The program is not easy, I am in the trimester program so it's accelerated but you finish in 1.5 years there's just no Summer. The program is doable, it's just a little rough in the beginning. Some days are easier than most, but I would 100% still recommend it.
Also, getting in the Spring is easier compared to the fall because there are wayyy less applicants.
