significantly

Hello,

I have 2 groups of pupils: group A and group B. In group A are 30 pupils and in group B are 32 pupils. Both groups do the same test.
How can I calculate whether the marks of group A are significantly better than group B? I know the solution must be easy, but my knowledge of statistics goes no further than the standard deviation.

example (scale 1-10)

group A group B
6--- 5
7--- 6
8--- 4
9--- 7
4--- 8
6--- 4
7--- 7
5--- 9
8--- 6
7--- 3
8--- 6
7--- 6
..--- ..
..--- ..

Thanks in advance.
