<p>purmou’s thread is still quite accurate, IMO. </p>
<p>My two cents:
Hardest majors in terms of difficulty (ie intellectually difficult):
Physics, Math, and Astrophysics (a superset of physics)</p>
<p>Hardest majors in terms of workload (ie lost of hard work):
ChemE (most requirements of any major at Tech) and EE</p>
<p>@OP, MechE is actually one of the easier options at Tech. It only requires ~192 units to complete and only a few of the classes in the major are considered difficult.</p>
