<li> By classes I don’t know if you mean disciplines or actual classes. By disciplines, the consensus seems to be that EE and chem E are generally the hardest. By actual classes I’m not sure, but I’ve always heard terrible things about fluids and especially thermodynamics.</li>

<li>I would say much harder, but again, I can’t say from first hand experience.</li>
