3 Years in a Non Target

I currently attend George Mason University as a Freshman. I recieved 32 credits before I started due to AP and Dual Enrollment courses in high school. Because of this, I will only attend college for 3 years, as most of my gen ed classes are already credited. Because of this, I realize the average 4 year plan is very different for me. I'd like some advice on what I should do next year to advance myself to an IB Analyst position after University. Should I just try transfer to UVA/Georgetown this summer and try to land an internship the next summer after which would be my last summer before my senior year. Or try to get an internship in a non IB field like wealth management and leverage it into an IB internship for the next summer? Any advice is greatly appreciated.
