I was pre-med for about 2.5 semesters and took pretty much all the intro stem courses. Being pre-med at highly selective universities like Penn was really hard and I was not doing well mentally. The class sizes are very big so I felt like I wasn’t able to get help when I needed on the course. The curve for pre-med classes are also very tough, usually the average is curved to a B- or B and everyone at the institution is so bright making the competition even tougher. The class time is also longer, I think I was in lecture for 3 hours a week, plus 1 hour recitation, and then plus lab which is another 3 hours, and then you add in studying, homework, and exam on top of that.
When I decided I no longer want to be pre-med, why business specifically? I knew I needed a major that is employable and that I can finish within 2.5 years (I was already done with sophomore fall semester by then). The pre-med classes all counted for gen ed or free electives. If I had started off with business, my GPA would’ve been much higher. But at the end of the day, it still all worked out and I’m definitely very fortunate
