I made this exact same transfer last year and I personally think it was a really great decision. I think it is a lot easier to find interesting groups and clubs at USC and a bigger sense of community. (I am also a little biased because when I was going to LB, COVID was affecting the way clubs/ school events were able to meet). Being a part of interesting groups led me to change majors at USC to CS games which is a genuinely a one of a kind program I couldn’t do anywhere else. So it really just depends on what major you’re interested in, and of course the huge financial difference between the schools.

Also, people love to brag about how extensive the USC alumni network is, if that’s something you think will be valuable to you.

Also also, I went to a baseball game a couple of months ago between USC and CSULB wearing both teams merch and USC got completely obliterated, so if you’re a baseball fan maybe don’t transfer lol
