I'm a first year PhD student in mathematics. One day I was having some conversation with my supervisor and we got to a point where he casually mentioned about his other students and said that one of his student is quite "weak" and one of his other student is "strong". Since then I've been wondering what does he think about me.
An obvious way is to just ask him directly, but the problem is that this country is Canada and here people are very polite (most of them). So, if I ask him directly, I think he will just say nice things about me and so, it wouldn't really answer my question. I would really like to have an honest answer, even if it's bitter, because then I would know what skills to work on and try to improve.
Can you guys suggest some better way to get honest feedback/constructive criticism from my supervisor?
Another vague question I have is: How can I know what he thinks about me? Does he think I'm a weak, mediocre or good student?
Little background: I have been working with my current supervisor since my Masters and I decided to have him as my supervisor for my PhD as well. We meet weekly to discuss about my progress/ideas and other administrative stuff (if there's any).
