Hi there...I may see some confusion here... When you have your spouse applying with you as co applicant 40 points automatically goes towards her from your share. If you do not want to use your spouse's points then at the end you will end up loosing the points in your overall CRS Score. Your education points will have a maximum cut off score. Which means even if you decide not to claim your spouse's points it will not help you get more points...In a joint application Primary applicant has their points and Spouse have their points. Completely separate and one does not out weight the other. They together combines gives you the overall CRS score. I hope that helps your cause.
