What I would recommend is having a single table with all of the columns.
Then create a form that initially shows only the Qualification Drop Down. When a value is selected the Form shows only the fields associated with that selection. You would do this by inserting an expression into the Show_If property of the columns that need it.
For example, the columns Course, Specialization, Type and University Name are all shown when Qualification = “Graduate or Diploma”. So for the Show_If on each of these columns, you could enter an expression like so:
[Qualification]="Graduate or Diploma"
But Passing out Year is shown for both “Graduate or Diploma” and “Xth Standard”. So the expression would be like this:
OR([Qualification]="Graduate or Diploma", [Qualification]="Xth Standard")
Having multiple tables and forms would become messy to manage and combining the data becomes more difficult if you need to produce comprehensive reports. etc.
Its way easier to pull out only the info you need than it is to combine the data later.
