<p>I heard from somboday saying...</p>
<p>Harvard student takes around 4 courses per semester,
spending 30hrs including studying and homework.</p>
<p>And about 70% of students take 1 ~ 2 ECs and
14% take 4 ~ 5 ECs.</p>
<p>I'm just curious...
What % of students take 5 or 6 courses/semester ?
The answer might be different, depending on people
and how many hours he/she also spends on ECs...</p>
