Pool Assignment Question - Small pool, multiple classes...

Hello,

I have a Pool of Linked-Clones but I want to set them up as 'Automatic Assignment' instead of 'Floating.'  The pool has 30 VMs in it.  If I have multiple classes of students using this pool each day will that work?  I want every student to get the same machine each day during their class period but I read that it is a 1:1 relationship.......can multiple students use the same VM as long as they don't attempt to use it at the same time?

Thanks!
