How To: Repeat CCK Field groups

Hi,
I am a recent fan of Drupal and already it's as much fascinating as overwhelming.

Problem: I am trying to make a Form asking for user education credentials. I am not able to find solution how to make user repeat a set of fields (Field Group) .

Eg: A student might have done education at 1 or more colleges. I want to present to your one "add more" button where he can keep adding as many schools as he wants. Each field group contains
1. School name ( Text field)
2. School Address ( Address)
3. Date Range of Joining ( Date)

I want the repetion of above fields by giving a option . "Add School" to the user.

Thanks for your time and help. Hope one day I will gather enough knowledge to give back to community.

Cheers!!
