In order not to miss anything, according to your reply, if someone, who has already had CLB9 in English, takes TEF test and gets CLB7 in each section, his crs score will ultimately be bumped up by 42 points?That's why the 15 points are pretty much irrelevant to anyone who is choosing English as a first language. Your goal are the 30 points not the 15.
Many thanks for your help.
