Is there anything I can do to increase my chances after the interview?

Well if you really want to go there you can write a "letter of intent" where you state your interest in the medical school and that you will matriculate there if accepted.

As for writing a letter each week, your Kaplan instructor is a psychopath. This would in all likelihood piss off the medical school with all the extra correspondence they would have to deal with. Don't do this, it's silly.

My advice is to write a thank you letter to your interviewers and write a letter of intent if you're really serious. I'd also send an update or two if there is anything significant you need to tell them. Keep in touch with them but don't be excessive and annoying.

 

once a week is too much. Writing something once a month would make more sense.

 

Excessively weird? YES! Don't stalk them. Just make sure they know that you are very interested in their school...

On a side note...was it the Princeton undergrad tour people who were talking about the guy who camped out at Princeton until they accepted him?... On another side note, I had the hottest tour guide at Princeton of any school I visited...
