<p>Reasonable, especially if you've had some calculus already and/or taken AP chemistry. If calculus is brand new for you and you haven't taken AP chemistry, though, I would lighten the load to give more time to devote to those two classes.</p>
<p>though the unit total sounds normal-ish, you have 5 classes. this would be a bit much for a first semester freshman, though it is definitely doable. if i were you, i would go for the first schedule you posted, or something similar to it with only 4 classes. chinese1ax, though only 3 units, is quite a bit of busy work each week, and thus it kind of disguises itself in terms of units. make sure to take this into account when planning your schedule.</p>
