By "ECA point 135", I assume you mean that you have a Master's degree ?
I also assume that you have no Canadian work experience ?
Did you score CLB 7 in each of the language areas (reading, writing, listening, speaking) ? Or did you score CLB 7 overall ?
Because the scores for each language area are calculated separately.
Assuming that you have a Master's, no Canadian work experience, and you scored CLB 7 in each of the language areas, I calculate your CRS at 307.
