Woo hoo CPC mod 4 passed , onward and upward 
Congrats. 
Well done Sir 
Thank you guys , daft question, do I send off my photo license , my test certificate and a d1 form , to get my license changed ?
If it is just Mod 4 you have passed then you don’t need to do anything your DQC will arrive shortly. There’s nothing to change on the actual licence.
Cheers for reply , what I meant was my driving license, hadn’t sent it off for class 2 entitlement yet , so do I get a d1 ?
