<p>An hour per day per 3/4 credit-hour class sounds about right to me. That’s what I did and ended junior year with a good GPA in EE. Although I’ll mention that: (a) I’m in solid state devices, which is physics heavy so it’s a lot of “you get it or you don’t” style conceptual problems and almost no labs (most other EE specializations involve large amounts of work that’s time-consuming even if you understand it). And (b) I have some very smart friends who I check all my work with.</p>
<p>The personality argument is ridiculous. The only “math robots” I’ve seen are a few Asian internationals and I suspect that it only seems that way to us because there’s a cultural disconnect. Pretending that people who do better than you have no personality seems like a way to comfort yourself because you can’t come to terms with the fact that you’re probably less intelligent than them.</p>
