I have an IELTS score of L:7.5, R:7, W:7, S:7.5 and I was wondering if I should write IELTS again to get 8777. I have one year of canadian experience in NOC 0, a post graduate deploma in Canada, 4 year graduation degree from my home country, 29 years of age, single, and I don't have any immediate relatives in Canada. Please let me know how many points I will add to my profile if I get 8777. Thanks!
