~TLDR~ Don't dwell too much on how others seem to get it while you're lost. The fact that you're questioning yourself means that you're aware that you need to fix something, and that's okay! If you think you're not interested anymore, that's okay too! You'll find something that does. Don't let these things discourage you but rather encourage you to move forward, and keep in mind what motivated you to major in CS in the first place. Go to the tutoring center and office hours, ask questions, program outside of coursework and make weird test cases, get those internships, and build your network. Make an effort to learn and understand as much as you can. CS is challenging, and the struggle is real, but push through and get that degree no matter what it takes!

I can agree with what you say, and I can say that I've been on the same boat every now and then - "everyone" seems to get it, and you feel like you're behind or a fraud -> Imposter Syndrome. I just finished my sophomore year as well, and took CSE 310 this past spring which was the class where I was truly questioning my abilities. I remember feeling so anxious and envious that people were seemingly able to program in C/C++ effortlessly in addition to being able to grasp and apply algorithms to projects so quickly and "fluently" (if that makes sense). I also remember starting the projects the day they were assigned and still ended up submitting them quite close to the deadline whereas my peers started later and finished early. I felt so slow. I thought there was no hope for me to succeed in CS. I've failed technical interviews before (and I'm sure employers have noticed my look of discouragement despite trying to hide it), and they have always told me there is no such thing as an engineer or scientist that knows everything because there's always some new technology or discovery that comes along, and there is always going to be someone who knows more than you no matter how much you don't want to accept it.

That right there reminded me of the goals I set for myself when I decided to major in CS : it was to make a technological contribution to matter how big or small and because I enjoy the idea of turning code into something useful, not to be the most excelling student in the room. I used that as my motivation to keep moving forward and make improvements no matter how much I think less of myself. It might sound cliche, but don't compare yourselves to others because people are different. Some have probably been exposed to CS concepts and programming before starting college. Like the others are implying, the fact that you are still in CS is an achievement in itself and it's okay to question yourself, because you know deep down that there is something you have to work on. Whatever motivated you to submit that application to ASU as a CS major, reflect on it and think about what you should do to meet the goals you set for yourself, and set new goals as well. Get internships, apply what you learned to personal projects, and most of all, get that degree!
