Im not sure about 14 weeks. I did mine over 19 weeks all 14 which was real hard going and the shortest course I have seen advertised.
In reality the average is 9 months, assume you will have to resit one or two. By the time you recieve your results you are unlikely to be in time to be able to apply for the following month hence time slips away! God bless the CAA and all those who shall sink in her
