What are the hardest engineering majors to get placed into?

I am a freshman in my first semester of general engineering. Aerospace was my major that I applied with. I am struggling with my classes and it looks like I am going to be getting all Bs and maybe one C. I want to switch to either Computer Science or Computer Engineering, but I wanted to know how hard it would be to get placed into those as my first choice majors since they are popular. Thank you!

@cerickson1 It’s too early to throw in the towel my friend on your first choice. Talk to your advisor. Freshman year, especially first semester, is one of the toughest. Hang in there. You aren’t alone in your struggle. Talk to your advisor. If you still want to change major, look online at the requirements and follow those steps.
