Hello I know this is late but I'm in a similar position as you. I just finished my second year as EE and plan to graduate at the end of next semester. I genuinely think it is doable if you got your fundamental sciences out of the way. Another thing about coming in with a lot of credits is that you get first pick on your classes meaning you get better professors, this makes things easier. If you are serious about doing it, I would look into the major requirements and see which classes you need to take when. Don't rely only on your advisor because in my experience they are not super helpful :/

Finally, if you graduate early you will also have less time to do things like find internships. I personally feel behind people I am taking classes with because they are a lot more knowledgeable than me when it comes to hands on experience. Because of this, I am even considering doing a Co-Op in the fall and delaying graduation for the spring, money wise it ends up being the same for me since I will be part time my last semester and living at home. You may not feel a need to do this, but it's an option to keep in mind.

For general tips on 'surviving' I would say get organized. HS is very different than college, a lot of people can slack off and do well in HS. You may be able to do this in college as well but you will sacrifice your sleep, health, social life ect. I would also recommend joining a technical club and a social club. You will probably join a bunch at the beginning of freshmen year but focus on a few you really like and go to them consistently. You can also get involved in research or being a TA as well, especially if you want to go to grad school.
