<p>cellardweller - I was was not speaking about Harvard overall, as I was only referring to the physics and math work that I have seen my daughter do. A sample size of one student is insufficient for me to make sweeping generalizations about the entire college. But I will say that the difficulty level of the physics and math work would likely be on a par with any other of the most difficult science and technology schools. After all, Math 55 at Harvard is regarded as the most difficult freshman math class in the country. The main issue to me in this thread is difficulty, not grades.</p>
