It is a cheap copy. For viewing, editing, and perhaps grading purposes
it is a copy.

You don't need a merge unless you want to combine the work back onto the
trunk. If this work is graded and discarded, you just need the
equivalent of a branch copy per student, which you don't have to call a
branch unless you want to.

They would be able to commit as often as they want in their own branch,
I don't see the point of the tag unless it is to signify that they will
not make more changes. Or perhaps, by omission, that they didn't
complete the task.

Aren't all versions unofficial, then?

You could use something as simple as committing a file of an agreed-upon
name into their copy of the workspace to signify that they are
unofficially sort-of finished.
