Even i jus had the same thought like you when i score less in IELTS (R-7,W-6,L-8,S-6) and my overall score was around 370. I had my brother in canada who insisted me taking IELTS again and again. I ignored it and was looking for job opportunities and universities to study instead. Later i realized that getting a job offer is not easy and studying involves a lot of money to be invested.
So i took the IELTS again but the difference is i invested a lot of time and prepared for just 16 days, day and night atleast 3 hours a day. I scored R-9,W-7,L-8.5,S-7 and the overall score was 450. I created my EE profile on 23-June-2017 and i received my ITA on 29-Jun-2017. The draw was for 449 points. I got selected by just one point.
My advise is just as everyone speaking in the thread, focus on your IELTS, you can easily score 430+.
Wish you all the best !!
