First of all, both your writing 20 choices are already full, so you can cross those off the list.
Not many people I've talked to recommend Chem 23L. Basically, the worst things about it is that it goes very quickly, goes more in depth, and worst of all, the labs are graded for
accuracy.
Also, the math department recommends that if you have AP credit (and are an incoming freshman), you take math 32 or math 41L instead of math 32L. I guess this is because math 32L is the second half of math 31L and draws on some things from that class. (

Since both of your writing 20s are full, I would highly suggest you take a seminar. I think these might suit your interests:
Schedule of Courses (only has 1 seat open!)
Schedule of Courses (the third one)
Schedule of Courses (all three)
Schedule of Courses Schedule of Courses
So, I would suggest you take Math 32, Econ 51D, and Spanish 63 on your MWF (econ also has a discussion section which can be scheduled accordingly), and then you can pick a seminar that will fit in your schedule =).
