I need assitance in a fallacy determination

Is this a good form?

If all As get B and
Some As are Cs
Therefore Some Cs get B.

I try to draw a Venn diagram to see if there's a fallacy problem but I don't see any. But I keep getting this feeling it's a fallacy...

Anybody knows?

This is a valid conclusion.
It helps to substitute the following analogy:

1. If all Students get Grades and
2. Some Students are Girls
3. Therefore some Girls get Grades

Also, some girls, those who aren't students, don't get grades!
