I have foreign BSW, second up, 83% gpa. With 5 years of full time international social work experience in the medical/health care field working for children with cancer and their families, and two years of full time research experience in Uni focusing mostly on family-centered practice (that's from almost 6 years ago). My references are a professor that taught me two courses during undergrad, post-doc fellow that supervised me when I worked in research and my direct manager when I worked as a social worker. Not sure if the references are considered as strong but they do write very nice things about me. However, I am sure most referees do try to write their best.
It's my first time applying and I was in Health and Mental Health Stream. Hope it helps, and all the best!
