    I was hoping you'd put in the infinite barrier/finite square well problem. As for what was on the exam, I liked number 6 - it was a question I didn't give much thought to initially, and was somewhat surprised a tangible result was possible.

    I agree with Edolfo. Particularly on problem 6 on calculating the potential from the ground state even though my potential looked kind of ugly.

    I also agree with edolfo. I wanted a half-well problem too.
    I liked problems 2 and 4 because they were more intuition-based, and, even though I'm not sure I got them correct, it's interesting to think that I have the intuition to solve those problems.
    And problem 6 was fun.

    i really liked #3 because I felt like it was a new problem to me but still do-able (and challenging). I think my reasons for liking number 3 are the same as other people's reasons for liking number 6. i wouldn't say 6 was my favorite though, because i got hung up on a small detail and didn't get as far as i wanted.

    I liked number 2-4 the most. 5 was cool too, i didn't mind grinding out the expectation value for x^2, but graphing a function like that is really, really hard if you made a couple algebra mistakes. i don't know if i did the algebra//Dirac thing right, because i got a solution which looked like the correct form, but not simple enough to put into a cosh, cos, sinh, or sin function. It sucks that you immediately lose points on part (b) if you made a few small errors on part (a) :(.

    Same problem for number 6 -- i know I had the IDEA right, but i might have made a derivative error because I had a really ugly function that was impossible to graph in the allotted time.

    Overall, a fair, good exam. Kudos.

    p.s. i think problem 1 was a little too rigorous, though.

    For me, in terms of mathematical comprehension of Dirac notation #5 was a very educative problem. I had not actually done so many repetitive steps using the notation, so I felt that it was a good experience.

    From a physical stantpoint, I appreciated problems 2,3 and 4, as they really tasted like Quantum.

    In problem 6, I did not have enough time to plot the actual potential, but I do not think it was a hard thing to do.
