Achieving above 480-500 points is possible but rare exception. Under normal circumstance by which I mean, an applicant who doesn't have French knowledge and Canadian experience could score maximum 498 points only. The majority of applicants are in 350-450 range. The cut off points will definitely come down in the future draws. It could go as low as 350, going further than this is also possible, but not certain.
