<p>I’m at Harvard right now, not sure what I’m majoring in (applied math? stat? economics/stat or math joint?)- something quantitative. Math 55 is generally considered by almost every grad math program in the US to be the hardest undergraduate math class in the country. IMO gold medalists spend between 25 and 60 hours each week on their problem sets. Trust me, if you’re interested in skipping ahead in order to get ahead in the mathematics world, Math 55 is the most impressive math class to have on your resume, if you can survive it (most don’t, even if they think they can).</p>
<p>If the reason you want to skip is that you’ve already done all of the material in 55 (which would make you absolutely insane), then you should talk to Prof. Kronheimer.</p>
