Medical to IB?

I read somewhere that WSO doesn’t feel like WSO anymore because we lack an amount of college kids begging to get into IB, so I’ve got a story for you guys. I’m a 3rd year undergrad student at a none target school (t100 lol). With that being said i actually entered college with wanting to do IB, realized my chances are low, left it and went to do medicine. Now my field in medicine has been bought out by PE and I can’t see myself practicing. I’ve got a good GPA, I’ve been applying to everything but I think I’ve regained an interested in this field. I’d love to do HF work at some point in my career. My question is how hard is it to work at MM IB? I feel like BB is always been impossible for most epitome to break in but why does no one speak about working MM, especially because I’d like to work in Florida being a resident there. Can someone shed some light into the MSF path into IB? I like vanderbilts program. Also if anyone is interested in talking please feel free to PM me:) thanks!
