I am in the US, and at my school masters and PhD students all take the same classes.

It is not ideal because many of the masters students are coming from a non-CS background. Some of the graduate level CS courses I have taken were easier than 4th year level undergrad classes.

This tracks well with my experience also. I was disappointed, for the most part, the several graduate CS courses for this reason.

By the time I'd finished graduate classes, I had a hard time with proofs. After the 10th or 12th introduction to predicate logic with slightly different notation, it just all becomes a big, confusing mass.
