I said that before, once CRS cutoff score comes down to 430s, not many people will re take IELTS for CLB 9 or 10 to maximize their score. They would rather wait for their turn and save some quids. My score is 443 and I canceled my spouse's IELTS test when I saw march 26th draw at 446! Soon you would see higher ranges are not filling up as much as it is filling up now because we can't have more than 3000 new entrants above 440 within 14 days! Currently many applicants from 420-440 ranges improving their score and entering into that fold which will not be the case soon!
If draw happens this week then it is quite certain that, CRS cutoff would be 438-439 and if happens next week then Cutoff would be 440-441! If they continue biweekly draws regularly and keep issuing 3500 ITAs then by June you should receive an ITA!
