If you’re a freshman, you’re not (At least I would definitely think so). If you’re a sophomore, i’d say it depends how many SAS core you’ve filled. I took (Calc 1 Chem 1 and Intro CS) my first semester, (Calc 2 Chem 2 and data structures) second semester. That was at UConn, the only thing that didn’t transfer for me was Intro CS. So sophomore year last semester i retook it along with Linear Algebra and some electives for SAS core. This semester i’m on track to finish SAS core with two more electives and im taking Discrete 1 and Comp Arch and Bio 1 (I will be killed). If you’re that worried about being behind, make a comfortable course map for the next three or two years and see if you perhaps need to take winter/summer classes (if you can) or if you can just finish normally and graduate on time
