it worked well. The credits transferred right to BYU and since I spoke Spanish on my mission, I took a 3 credit Spanish course and a 16 credit Spanish test which I used towards the 24 credits (I took other classes and had some other credits from a semester at BYU-I) that you need to get into BYU. I think it’s 24, but I’m not sure.
This was a few years ago, so I don’t know if that is still the requirement. Best of luck to your kid.
