It depends upon your overall CRS score, sometimes if your profile is strong enough to get through even on a low band score in Ielts Better ask from your consultant whether you can get through with this score or not.Best Aggregate Score is 7 I have also heard that someone was through with 6.5 but it sponsorship case. Kindly ask your consultant to count your score based on your education, age and experience etcetera and then it will be right to judge whether Ielts Score of 6.5 is OK for you or not.
