Re: 2NF but not 3NF
It's not in 2NF because of the functional dependencies.

Name is a function of StudId, that is, given the StudId, you always know what the Name is. So to get rid of that dependency, you'd project away (StudId, Name) to another table, and only have StudId in the original table.

There are others there, so work those out before you try to understand 3NF.
