Yes, I definitely understand you. Luckily, I also came out of undergrad debt free, but for that same reason taking out such large loans for my first time is even more the scarier.
Out of the schools I applied for I also had the most difficulty finding information about CSULB, which was disappointing. Their website was underwhelming. Some of the info that I got from the interview open house:
-it's a 5 semester program, no summers, and you don't have to take any extra classes (in case you were a post-bac student)
-they have a multicultural emphasis & offer a bilingual certificate I believe
-they have on site clinics & you also get 2 off site clinic placements
-mon-thurs classes, with classes usually being in the morning and clinic after
-they mentioned there being an open door policy with professors and an emphasis on collaboration
-the current students that spoke about their experience all seemed to be happy with the program (but this seems to be the case at every school lol)
You probably already heard this information as well, but sharing just in case. Idk about Biola, but in my case Chapman had an abundance of organized and detailed information on their website, which was very appealing. I wondered if CSULB maybe was lacking this because they're a state school and might be tighter for funds? But even CSUF had a lot more information on their website. Anyway, I know it's a tough decision, especially when you're paying so much, but good luck! It gets said a lot, but at the end of the day I'm sure we'll get out of any program what we put into it.
