Grades:
CLASS GRADE=0.2*PS+0.3*M+0.5*F
where PS is the grade of Problem Sets, M is the grade for the midterm and
F is the grade for the Final. The grade for the midterm will count ONLY if
it is favorable (that is, if M>F, then M gets 30% of the weight and F gets
50% but if M<F, then M gets 0% and F 80%).
