Do af fergusons & co accept cv with group ! clear...??

You dont have provision to directly apply to AF Fergusons. It is now part of Deloitte. You can apply in Deloitte website if vacancies for Articles are available. Even with 1 group you can apply to Deloitte, but usually Big4s gives priority to both groups passed students. If you have known reference there, then applying with 1st group also will work out.
