<p>I’m told that 61A is the more time-consuming of the two. E7’s also the more useful of the two - Matlab has practical uses, whereas Scheme is useful pretty much only for teaching people how to write code. If you’re not planning on going particularly far into programming, 61A really has no practical use and will likely be more work than it’s worth.</p>
<p>I honestly wouldn’t recommend either alongside 4A unless you’ve got good reason to believe you’re pretty good at programming, though. The Chem. E. who did E7 did pretty well in both, but as noted, his first semester didn’t involve a whole lot of sleeping, socializing, etc…</p>
