Hmm this thread is almost dead but I'll post anyways...
I currently attend an HBCU but i got here purely by accident, never applied, I was just offered a scholarship and was like "What the heck"
But i regret that decision and I am transferring to a PWI next semester. Here's my experience in a nutshell.
-I came from a small predominantly black country so it wasn't much of a culture shock
in terms of size and color.
-Being the best at an HBCU school has a lot of benefits. For example many big companies/schools will intentionally seek out black students in order to meet a certain diversity "quota" (couldn't think of a better word)
Cons (these are cons for me and I know not everyone has the same problems)
-I didn't like the overly afrocentric culture. Like being forced to take african-american history (although I point blank refused). And everyone saying "oh because I'm black this, or black that"
-It's probably just my school, but there is a really disrespectful attitudes among a lot of the students. They are openly rude to professors and don't seem to care about their work at all. (although this could probably be found in lower ranked PWI's)
-The music. Not a really valid point, but I just couldn't stand the "black southern" music everywhere
-Lack of organization and funding. I am heavily into research and our labs are just not up to par.
And that's basically my experience. There are a few other points but I just can't remember them now.
