How much credit would YOU have given me?

I had to explain the Hall Effect and derive the Hall coefficient

I didn't recall what the coeff. was but my explanation was solid and I was able to derive the Hall voltage, Vh=BI/net (t was thickness of plate, that's n and e, not the word net >_>)

I wrote that I didn't know what the coefficient was, and guessed 1/net

he's a pretty loose teacher, and getting to the voltage expression was the hard part anyways, I figure...

Without more details and a better explanation of the context, I'd swag about 7/10. What did you get? Was this on a midterm, final, quiz, what? Which class at what level?

A final, so I guess I'll never know :( senior level solid state class, 20 point question, I figure 10 for the explanation, and however many he feels like giving for getting to the voltage? I know, I obsess over how I did on a test after the fact, stressful habit
