I'm applying for master's degree in mathematics (pure math) at Canadian universities.
I already found two professors to write academic letters for me, but it's hard to find the third one who can write a strong letter.
All schools mentioned on their websites that they require 3 letters with at least two academical references which means the third one could be professional.
I've been working as a math tutor at a community college in Toronto for past 3 co-op terms. She has supervised me for 2 co-op terms and knows me very well (even more than my professors).
Her position is Learning strategists - math specialist which means her job is to support students' learning and deal with their academic concerns. Before the current job, she earned her master's degree in mathematics and statistics and worked as a lecturer/teaching assistant at a university for 5-7 years and was an instructor at the current college for few years. I don't want to reveal too much about her, but at least I can say she went to/worked at top Canadian universities.
I have built good relationship with her as a co-op student & supervisor and I have some impressive achievements in a college tutor level. So I believe she can write a strong letter for me.
My concern is she doesn't hold PhD. Would committee take her letter seriously? Do you recommend to get a letter from her rather than from a professor who barely knows me?
