As part of the new CPD requirements, do I have to do a Group 3 activity?

Group 3 activities are not mandatory. 

Pharmacists undertake a variety of activity types and where possible, choose across a range of CPD activity groups. Group 3 activities attract 3 credits per hour of activity because they involve facilitating quality or practice improvement. 

However, pharmacists will meet their CPD requirement if they undertake a range of Group 1 and Group 2 activities.
