I genuinely can’t tell if this is serious.
I’ll be blunt - this is an incredibly, incredibly stupid consideration for many reasons.
To summarize the highlights:
1) Match lists don’t matter. If you weren’t going to match at your current school, you probably weren’t going to match it at Harvard, either. There is some prestige factor, yes, but much of the onus is on you.
2) You have a GUARANTEED acceptance right now that you are willing to throw away. I think that is ridiculously stupid. You may be very confident, but you are throwing away 100% for less than 100%.
3) You are liable to change your mind in medical school. You currently likely have less than a tenth of the clinical experience you will have at the end of med school and that is being very liberal.
