limited registration confusion

Hi There, can anyone shed any light for me on limited registration please! I have managed to find an employer that can employ me under these terms, I also have sent of the application for assessment for limited registration which is curently being processed. I am now trying to fill out the last part the actual limited registration application ready for when the APC hopefully approve my skills to work in this employment. I am confused as the limited registrationa application just says i need to get my empoyer to fill out the back two pages of the form, write a letter saying they know and accept there responsibilities as a supervisor and finally a letter saying why they need someone under limited registration in the public interest. This i can do.. however in the procedures of supervisors documents.. it states before i start employment i need to fill out part A and B to assess my competence and make a supervision plan with my employer. How can i have my competence assessed if i am not allowed to treat pateints yet as im not registered? and also im not in the coutry yet as i start my job a week aftre i get there?! does anyone understand this process or have completed it? as i leave the country in 2 weeks and need to sort it all out before i go, i thought i was all sorted with a job and the app going through.. now i feel a bit stuck?!! help?! has anyone else applied for limited registration since the new rule changes last june and can help me out?! urgent please help!! email: [email protected] or post on here!
