Hey there! Congrats on your admits!
Masters programs are tricky for a pivot as you have only a year (let me know if these are 2-year programs) and often lack an internship that gives you a foot in the door, just FYI, thus having a good ROI is important in case things are tough.
Having said that, I am not sure how recruiting works for IB and if it is completely off campus and online/in person does not matter?
I feel the online program is always dinged by employers and people and even if you work just as hard it is regarded as less capable and easier to get into and thus less prestigious.
P.S. Both Fuqua and ND are in small towns so likely all recruiting happens on a trek to NY, Chicago, or Charlotte?
I would recommend to see if there are recruiting programs/pathways established at Duke or ND or Georgetown and if there are patterns for where other students land. I take it most are likely going straight for UG?
