@SabrinaKim This is not true. The EE profile automatically assigns points according to what is inputted into the EE system. Therefore, if you put a foreign bachelors then you put a Canadian post graduate diploma/degree it adds up the points automatically. There is no option for 2 or more certificates, diplomas or degrees to select as it is automatic. If you completed the post graduate degree in Canada, you get additional 15 points in addition to 128 points for 2 or more. If distance education, you just get points for 2 or more certificates, diplomas or degrees.
You wont need to have your Canadian education assessed but you would need to provide copies of your transcripts and diplomas/degrees for upload once you receive ITA.
