D.1. How comfortable
are you using calculus
D.2. How comfortable do you
working with statistics and understanding what things mean?
(Note that I'm not asking how much you know)
D.3. How comfortable do you
working with probability and understanding what things mean?
(Again, I'm not talking about classroom knowledge. Maybe you learned it
all playing cards)
D.4. In general, how comfortable
are you figuring things out. Like how to slice a bagel so
that each of three people get an equal part, and everyone gets a hole.
