It differed quite a bit. There were a handful that put in the same effort as I did and the few I've kept contact with are doing quite well. I'd say that just over half of the students stuck to core hours and most of them didn't make it through the bootcamp at all. I recall that many of those that stuck to core hours and graduated had some programming knowledge already or were exceptionally smart.

About a quarter of those that graduated in my cohort are in the IT field, but are project managers or something similar.

The bootcamp was in 3 phases and you had 2 chances to test out of a phase or you'd be kicked out. Of my starting cohort of 16 people, 12 of us completed the bootcamp. Our cohort grew to 22 people though because there were people that had repeated phases to complete it.
