University Exploration Program?

Hi,
My son was accepted to OSU into the University Exploration Program. Although he isn’t 100% sure what he wants to major in, he is leaning toward Psychology. Does anyone know if this is an easy transfer after starting by end of first year let’s say? Or if he should try to switch into that major before he matriculates (if he ends up attending)? I guess I don’t know too much about the program. Thanks for any info!

Yes, it’s easy. http://exploration.osu.edu/

All undecided students start in Exploration.
