Rollups are used when you have a master-detail relationship and you want to use information from the child records on the master one, like for instance how many children does it have - COUNT. 


IF the relationship is just a simple Lookup then you can use a trigger. 


Why can't you use a master-detail relationship and rollups? The trigger should be the last option.


To which object is your Student related? 


Thank you,
