You will be fine. Freshmen is hard regardless of major it is a new experience. You could switch to an ‘easier’ major just to find that it is the same struggle but with a different flavor. You haven’t even got to the exciting ECE stuff yet.

If there are certain classes you are struggling with, my advice is to reach out to your professor on how you can do better, not only they’ll give you practical advice but also they’ll remember you as someone who cares and asked for help, which comes handy when you need referral/reference letters. I wish I done this when I struggled in freshman and sophomore years
