<p>Hi Pannaga,</p>
<p>Regarding credits- Please understand that there is a big difference between what is Advanced Standing and normal concentration requirements. Advanced Standing is used for graduating the college in three rather than four years, and is most often taken advantage of for financial or similar reasons. However, most concentrations won't let you use AP credit towards their requirements.</p>
<p>There are exceptions- a few majors have requirements that can be placed out of using AP credits. The most common example by far is using BC Calculus to test out of Math 1a and 1b, which would otherwise be required. Examples of concentrations where this is true are Applied Math, Astronomy, and Computer Science. Some concentrations, like my own Statistics, require 21a/b, which therefore require 1a/b or the equivalent AP classes.</p>
<p>In the case you're interested in, Neurobiology, an AP math credit won't reduce the number of courses. From the FAS handbook:</p>
<p>"Two half-courses in mathematics (above the level of Math 1a; ordinarily these courses include Math 1b, Math 19 series, Math 21 series). Students who place into and successfully complete Math 19a (recommended) or higher need to complete one math course; this does not reduce the total number of courses for the concentration."</p>
<p>So while you can skip 1a/b with an AP BC calculus 5, you'll still have to take two math courses. As for chemistry/physics, they require three courses "Physical Sciences 1, 2, and 3; Chemistry 17, 20, 27, 30, 40, and 60; and the Physics 11 series and Physics 15 series." None of these would be granted for AP credit for either chemistry or physics. The requirements would be the same.</p>
<p>You might be thinking about Economics. I again quote from the Handbook:</p>
<p>"Students in the classes of 2011 and beyond may use AP or IB scores to place into 1010a, 1011a, 1010b, and 1011b, but they must replace Social Analysis 10 with two economics electives. Consult the Department Handbook or a concentration adviser for details."</p>
<p>Since you'd clearly be in a class after 2010, your courseload wouldn't be any lighter if you'd taken AP Micro or AP Macro in high school. Courses like the Statistics requirement generally could never be replaced by AP Stat.</p>
<p>So for neurobiology, it's unlikely that any of the AP courses you've taken will put you closer to the concentrations. They're still a good idea- several let you take more advanced classes to cover it than otherwise- but in the case of neurobiology, you'll be taking just as many courses.</p>
<p>I hope I've been helpful. I'm really glad to see you're this specifically interested in the curriculum at Harvard and other schools.</p>
