I recently took ielts and my score was L9 R7.5 W 7 S 8. I would have 1 year of skilled experience in Feb 2017, and I am turning 30 in April 2017. If after completing my 1 year, I would be granted 450 points, however, if I won't get an ITA before April 19, 2017, I would lose 5 points and that would bring down my CRS score to 445. So, should I retake ielts to try scoring 7.5 in writing and 8 in reading? Well I know that 450 is nothing looking at the current trend but if we see the trend from last 1.5 years, there were some draws in which cut off was 450 but not below. Please advise
