My career only goal is to get involved in research (PhD). My previous education, working experience (teaching) and publications help me to get admission in a Master program at a Canadian high ranked university. However unfortunately I got a FZ grade in one of an elective course (I was extremely mentally upset on the final exam day due to family issue) though I took another elective course to meet the programme requirement. While coming to PhD application, my supervisor informed me that my chances of not being accepted in the PhD program at the university is high since I have a FZ grade in my transcript. He also told me that he will write recommendation for me if I try to another university. My question: can anyone please explain me how much does this FZ grade (though I have replaced the credit with another elective course) will impact in my PhD application in future?
