thanks. can you give me any advice about how should I write my letter of explanation? my reason was that dental hygiene focus much more on prevention and I didn't study it during college, so I need this to better my current employment situation and also to teach this program when I return.Algonquin college is one of the best public colleges in Canada. Not only for International students but the natives/ Canadians students also prefer Algonquin over other colleges. It is in heart of the Capital city Ottawa.
