Alright how would you have me fix it then Hero? Just scrap the idea and make a whole new character? I'm asking genuinely not trying to be a smartass.

This is your character and it's someone you should be happy roleplaying; that's first and foremost. Hero and my purpose for examining what you have is to see if they would be a good fit for the themes of the RP and if they would make an interesting dynamic with the other castmembers. 

So if you want my ideas on how to narrow the character's focus, let's look at good character arc ideas and build from there. First: he's a rich kid; family owns a big corporation, there's a lot there. They have ties to the medical world and maybe he's invited by the school due to the research hospital's connections. He could be interested in new medical technologies and wants to make radical new changes to his family's corporation: whatever his goal is is important. And yes, we've looked at the backstory stuff you want to keep in the dark; which is fine. I think that kind of backstory feeds well into his desires and where he may go with the ideas of medicine. 

Let's also take into account this: he grew up rich. That means that he misses out on things that 99% of kids do growing up, due to his status. Ultimately there is going to be a disconnect to what he knows about life and what others know, due to that gap in privilege. That leads to interesting character dynamics, as he may feel disconnected from the other members of the group because of this. It could also be a source of comedy as he struggles to understand the more "baser" things in life that aren't as cultured as his upbringing. 

Again, none of this is me telling you how to make your character. That's your decision. But these are just ideas I had in mind on how to give your character more focus with their personality and backstory.
