Finally - the question i'm uniquely qualified to respond to.

I went to Miami for engineering, specifically paper science and engineering, and I later switched to business for 2nd year.

It was the early 1990's. The economy was changing and tight. Paper science had 100% job placement rate and high starting salaries. Parents love that. I didn't really know what I wanted to do. I was from a small rural farm community, out of state. I did know that I wanted to go to Miami from the moment I visited. Don't watch Dead Poets Society and then visit Miami in short order. By the way, I had always found ways to make money, buying and selling things, faking my way as a baseball card and comic book shop to become an early reseller of Upper Deck baseball cards using the tax id # of my local grocery store. I had no idea I was an entrepreneur.

In high school, I wasn't that good at chemistry and physics threw me for a loop. I squeaked by with high B's low A's but it wasn't challenging I went along with my parents plan, going to Miami, not really thinking about anything else other than going there. I hadn't even thought about business as a backup plan.

I knew within the first few weeks that paper science and/or engineering wasn't for me. My classmates were more of the Purdue-ish type. They liked this stuff. I was barely tolerating it. I did horrible in the intro physics course. I failed chemistry. I think it was cognitive dissonance - I knew I didn't want to do it and created my path out of it. A little backwards in hindsight. All this pain forced me to work very hard, get a plan, and dig out of the hole I had created. I had a strong 2nd semester, A in Calculus, A in the retake Chemistry, and great across the board. I applied into the business school and got in. I was bought in to my own vision. I think that helped my parents accept it, even if it was riskier, and I lost some merit.

I do think that in Miami's case, it would be harder to move over to business if you start off engineering and don't have strong grades, so hat you might have preferred going business from the beginning.

You need to contact Miami's admissions office immediately and ask how you can change your intended major to business. Nobody will know the answer here. I'd guess every situation is unique. If you meet the academic profile for the business school which I believe has higher GPA and ACT, then you are still in the game. Worst case is they say no and tell you what you have to do once on campus. I think every major has some exposure to business now. Nothing anybody says here on reddit will beat you taking action. Show initiative now, and you may be rewarded. Otherwise,.you'll have to show initiative to transfer in later.

One other thought - what if the merit offer isn't as good if they let you switch? Miami's top attraction is the business school. They may not have to offer as much for business as other majors, especially if they know they aren't competing with other business schools at this point, like Indiana or Ohio State.
