Maybe you should do it with Javascript prior to submit the form.

Anyway, what error are you getting?

Is any of the options selected?
Did you consider doing this with Javascript?

I would make sure when the page loads to force a radio button to be checked as default. You do this by adding:

checked="checked"

inside one of the radio buttons. I would do this for both radio button groups.

Also on a side note, you should be closing your input tags. You should be doing:

<input type="radio" name="r1" value="r1" />Graduction<br/>
<input type="radio" name="r1" value="r2" />PostGradution<br/>
<input type="radio" name="r1" value="r3" />other<br/><br/>
