Taken MCB 104? MCB 163? Difficulty..

<p>Hey, just wondering if anyone can comment on MCB 104's difficulty? Not sure if I should take it MCB 163, which I heard takes up a lot of time.. Or would MCB 104 + MCB 163 be doable? </p>

<p>On a side note, I'm considering not doing MCB at all, so I could avoid damaging my science GPA any further :.. but can't decide, since I truly enjoy neuroscience!</p>
