<p>Planning to take some courses over the summer to get a head start into college. I'm currently signed up for Math 54. I'm thinking about taking a second class, and I'm thinking between Stat 2 and Stat 21 (particularly after I've missed three opportunities to take a statistics course). I've taken calculus, and from what I've heard, Stat 21 and Stat 20 should vary by their titles, so I don't think it should matter that I won't go into business. I've also heard some notorious comments about Stat 21, but some/most of them were concerned with professors like Purves. How are Stat 2 and 21 different, and what would be the better class to take?</p>
<p>Also, I didn't receive any financial aid from Berkeley for the fall and spring semesters because our family's income was too high (although I do have demonstrated need). Will there be a point in applying for financial aid for the summer session?</p>
