Does anyone know about how the USAMTS graders feel about partial solutions? On a couple of problems in this round I just did as much as I could and just left off.

Partial solutions are OK, I think, but they'll only get partial credit. Here's the grading scale:

5/5 = clear, concise, correct solution;

4/5 = minor shortcomings in the solution;

3/5 = larger holes in a promising solution;

2/5 = some good ideas but not much more;

1/5 = evidence of understanding the problem;

0/5 = nothing presented that is credible.

I would expect you would get at least 1 or 2 for a partial solution.

I was surprised by how much credit you get for having a partial solution. I got the wrong answer for 2/5/15 (the solid with minimum number of faces) and still got 3 points for it. On another one, I didn't have a rigorous proof and still got 5 points. Go figure.
