I'm about to start my 5th year at Xavier University (Cincinnati, Oh). I switched over to physics from chemistry before my 4th year because I hated my 2 years in chemistry and had been interested in physics since my senior year in high school, but didn't really consider majoring in it at the time.
1. My life was pretty busy during the school week last year due to me taking sophomore and a few junior level physics classes. I assume it will be even more busy this year since I'm trying to finish up this year with the remaining junior level and all of the senior level classes.
2. I very much enjoy my degree. My school's physics department is small (roughly 40-45 students) so I have met a bunch of people which is great since I didn't know anyone at the school until this past year. It has been challenging, but I would trade it for anything else.
3. All of the labs have weekly reports associated with them for the different labs we do. I've had a couple of long papers formatted like they were going to be submitted to a journal.
4. My school does not offer engineering so that wasn't an option. I'm not sure whether I want to go to grad school and if I do it wouldn't be right away. If I do go to grad school I'm not sure what specifically it would be for, I could master in engineering if I wanted to down the road.
edit: I also went from a B-/C+ student for all my gen ed classes to a B+/A- student in Physics for the most part with friends, so that is probably the best thing to come out of all of this.
