No problems but still sit for other two papers too if you have already prepared.
To claim exemption in a subject u need to sit for that group totally and not for both. So as someone said when u r being so confident and enthu about the theory u should definitely try for to aggregate through those 2 subjects and worst case scenario aggregate doesn't happen. Nobody can take away the right of exemption from u if u manage to secure in theory.
