SC1003 vs IE1005

Hi guys i am an incoming freshman for IEM, and i decided to sign up for the trailblazer thing for nsmen (dont ask why pls haha) my first choice was sc1003, but as i was looking at my y1 schedule i will be taking IE1005, "From computational thinking to programming" which sounds v similar to SC1003 "Intro to computational thinking and programming". anyone here can tell me whats the difference between the two mods and has anyone taken both? srry if i sound like the kiasu type
