<li>It really depends. Humanities classes are generally not competitive, and grading is typically done on an absolute scale (as opposed to a relative, curved scale). Many students in reading-intensive courses often collaborate with one another, splitting up the reading and sharing summaries. That requires a lot of trust and teamwork. </li>
</ol>
<p>Science courses are also, on the whole, not very competitive. The only exception is pre-med courses, where “getting the A” may have an important impact on acceptance to medical school. For example, Physics 11 is a pre-med requirement, and the students in that class generally do not work collaboratively (unless it is necessary if the material is too difficult for them). On the other hand, in Physics 15 and 16, the more rigorous, non-pre-med courses, collaboration is everything. You work on your problem sets with your classmates, you have lunch with them, and every Thursday you head to Leverett House dining room to work on the Physics p-set and eat cookies and milk (even the very intelligent students who don’t really need help on the p-set go, unlike in Physics 11). </p>
<p>So I would say that the classes in general are not competitive, except a spattering of pre-med courses.</p>

<li><p>I think it’s better to have a few activities that you are truly passionate about. 17 ECs is absolutely ridiculous and screams a lack of commitment. If you can convey your passion for those four ECs, it is exponentially better than 17 cardboard ECs.</p></li>
<li><p>Yes, there are the Breakers and a lot of other groups. Any group you can think of (although, now that I think of it, there’s no competitive eating team).</p></li>
<li><p>Yes, I have met many famous professors so far, even ones that teach courses I’m not taking, including Niall Ferguson (teaches this Gen Ed course called Western Ascendancy, very dramatic teaching style), Greg Mankiw (teaches Ec 10 and a freshman seminar, was Bush’s economic policy advisor, very funny guy), Alan Dershowitz (teaches a seminar that my friend is in, defended OJ, very self-righteous but cool), and Howard Georgi (physics god, very quirky and intelligent, cool guy). But the teachers that have the greatest impact on you will not always be big names. </p></li>
<li><p>Of course not. That is, unless one has no chance in hell (not your case). Then one would be wasting 70 dollars, which I guess hurts.</p></li>
<li><p>I’m not sure what you mean. It sounds like you haven’t taken this APs yet. If so, then on the Common App I believe you can put the test, the intended date of taking that test, and a blank line on the score. </p></li>

<p>Hope this helps!</p>
