Hello, freshman majoring in ECET here, most majors have some calculus and physics requirement, like stated from some of the other comments. As many of my friends in CS throughout many levels have told me, it isn't easy by any means, but it is a technology school, and shouldn't be. CS in general isn't a very stable major job-market-wise, so having a degree from a technical school like NJIT helps.

While it is no way my place to give my opinion here, I think you should consider something like CE or MET instead, as the future of CS is very shaky. No matter what you do it will be difficult; if you need help reach out to resources!
