 I got the same as Liux, Andromeda, and Devlin. I got the same as Liux, Andromeda, and Devlin.
 +===Hydra 12/11===
 +That's what I was getting, but is there more work to show for this?  It seems, .....too basic???
 +===Dark Helmet 12/11==
 +Where does the root2 come from?  It seems like this whole problem can be done just by reasoning except for the root2.

 I would agree with the previous two comments; it's just a sample of what we should know how to do for the exam. This last section since the last exam has covered quite a bit of material, and there's a lot that we can do with it, so the example problems are meant to be a supplement to studying: if you can sit down and do the example problems without outside reference material then you'll do well on the exam. If you get stuck on a certain type of problem then you know that's what you need to work on before the exam time. Also, each exam in the past has always had a problem that's very similar to one on the practice exams... I would agree with the previous two comments; it's just a sample of what we should know how to do for the exam.

 +===Devlin===
 +Also, I don't see a question in number 4, just a bunch of statements.
 +
 +=== Zeno 12/11 ===
 +Yeah, this puzzled me as well. I think we're being subtly asked to find the normalization factor like in problem 4.18 from HW 10.
 +
 +===Dark Helmet 12/11===
 +I didn't see one either, maybe it was just useful information??
 +
 +===The Doctor 12/11===
 +I just assumed it meant to show how to find it using the given relations.
 +
 +====Hydra 12/11 post-test!====
 +Hey, how do you do the first exam problem from today?
 +
 +===Blackbox ===
 +Well, it was difficult for me and I have no idea what I have to say about the test.
 +
 +====Dagny====
 +For first order theory, infinite square well, how do we know when to integrate over entire well or just parts of well?
