<p>If I'm applying regular decision for MIT this year, could the AMC scores
of next year possibly impact the decision? For example, if the committee looks at my application later than others, could my AMC score go in?</p>
<p>The last time you can really send supplemental information is early February – the admissions officers go into selection committee around Valentine’s Day, and decisions are finished by early March. Information that would come during selection almost certainly wouldn’t make it into your folder, and admissions officers don’t discuss the applications in a linear order anyway.</p>
<p>Sadly, it probably wouldn’t help your case unless you made the IMO team…</p>
