<p>I've decided to drop out of most colleges for the match round. Do I need to contact each of the six colleges that I'm dropping out or will the updated QuestBridge match agreement form and simply not submitting an application do the trick? I think I read on the forums that someone got taken out of MIT regular decision because they didn't email MIT saying that they would be dropping out of match and doing RD. I'm still doing match for MIT, but do I need to watch out for that with other colleges?</p>
