tariq bhai ye kis assignment ka solution hey...mera khiyal hey ye cs403 ka nahi hey

This is not the sure solution...only i want to discuss about my solution if u find me wrong please inform me...!!
to convert to 2NF make 3 tables following dependencies as
1. (Student-ID, Specialization) -> (Specialization Semester, Semester Start-Date, Semester End-Date)
2.(Student-ID) -> Name
3.(Specialization) -> Specialization Supervisor

To make 3NF remove transitive dependency from the table "1"

i.e Specialization -> specialization semester -> start date , End date

and make them in seprate tables.
