I have positive assessment from ACS for 263111 - Computer Network and Systems Engineer and will be eligible to apply from Aug 2017. I would like to know if i can write IELTS Academic for migration purpose. Is IELTS Academic also accepted for 189\190 visa?

I got overall 6.0 bands in IELTS and I would like to know is there any alternate options which can help me to submit EOI and SS with this result? L 6.0 R 5.5 W 6.5 S 5.5 I already got positive result from ACS for my assessment. I know that 6.0 aggregate is required however I would like to know...
