getting married.. brings your score down by more or less 20 to 25 points. if you want a Lum sum idea. Thats why you have things like ECA for spouse, IELTS etc to makeup for that loss of points. For example my case.
points without wife: 429
with wife : 407
but I had job offer with LMIA+work permit =457
