I submitted my EE profile on 24th April and my initial score was 447 but i checked my profile on 9th June and found my score has increased to 472. I know this is coz of completion of 3 years of work exp. According to my calculation i completed my 3 years in first week of may, however my score didn't increase at that time.So I am confused about the timing of change in score.
Secondly, I am going to leave my current job by end of June. So when should I update my CIC account??
The system is on MM-YYYY format so it probably gave you those additional 25 points at the end of May/beginning of June.
Update it after quitting. The logic there being - if the act of quitting your job doesn't affect your CRS score then CIC really doesn't care about your current employment status.
