I have applied for permanent residence federal skilled worker on 10 of June, via the NOC 4121 and 7213 . and now I am preparing my documents to send to visa office . I have worked experience in 7213 for 3 years full time and in NOC 4121 I have experienced one year as a full time professor and 6 mounts as an part time professor, since my brother lives in Canada , I am above the 67 score , But I made a mistake , I was assisting the professor while I was educating  for 4 years as a part time job, I mentioned them in my form schedual3,just to show my activity during education ,and I thought it means assistant professor with NoC 4121 , Now I understand it was teaching assistant with 4122 NOC, should I change it now??or should I write a cover letter that written it means professor's assistant or who assists the professor ??
what shroud I do Huh
I heard if I correct the NOC the officer will reject the case with out interview??
How can I inform the best way ?
