<p>Very manageable, I took multivariable, linear, mechanics and 2 other humanities, and still had plenty of sleep + free time for other activities. For multivariable, I recommend reviewing all the stuff in AP Calc AB because it’s just higher-dimensional of those stuff. </p>
<p>For linear, KhanAcademy is your friend. In my experience, most lower-division linear alg teachers really suck at doing examples in class and just instead ramble on proof and such. Khan does the other way around - lots of examples.</p>
<p>Mechanics is pretty easy so don’t worry, so as differential
E&M, Relativity/Waves/Heat can be challenging, so be prepared for those classes. </p>
<p>Hope that helps. Very manageable and doable in 2 years, as long as you stay on top of the material and understand what you do. P/NP the humanities (not English) if you can (check Cal EECS policy, I’m not sure) and spend time on those technicals since they play a huge part in your admission to top universities like Cal</p>
