given your academic performance your language ability in specific bands and considering your proposed course of study your travel history and ties to your home country im not satisfied you would be a bona fide student and temporary resident[/QUOTE
As per my understanding, your academic credentials are not so good, overall your IELTS band score is 6 with one module may be 5 or 5.5. The program level you selected may be not in line with your previous studies or progression level, rest are expected as usual. However, it is better to apply for
CAIPS / GCMS notes for actual reasons and better understanding. Finally, better to share your complete profile to get better suggestion / recommendations from Senior Members of this forum.
