Artcileship termination after 1 year

My son is a direct entry student and has completed articleship for 15 months.  He would like to terminate his articleship as he woule like to take up employment for some time.  I have the following questions:

1. Can he submit form 109 by mutual consent, though its beyond 1 year if my auditor is agreeable to this.

2.  Will he be able to take up group 2 in IPCC, after submiting form 109, since he has completed the required nine months of articleship

Please advise.

Regards
