<p>Hardest at which to succeed or get good grades? I’m sure that grades are hard to get at Cal Tech, but success at Harvard is measured in equal parts formal curriculum and extracurricular. There’s a tremendous social press to not only be ultra-involved in EC life, but to achieve incredible things. Students there write, stage and perform Broadway-quality musicals in under a year, coordinate international youth symposia, begin soup kitchens and homeless shelters and tutor disadvantaged youth. I’ve seen things go on there that I can’t believe were generated by college students, much less college students operating with very limited professional advice or support, much less autonomous college students carrying a full load of Harvard classes.</p>
