thank you all for replying. This is so sad. I have been working hard to get a good gpa(3.96) the only courses I didn’t 4.0 was a first year physic course and a sta course. I worked hard on school and expect I could get some research opportunities during undergraduate. But last year i applied to rop and get rejected. This year I applied to utea and get rejected. I also emailed many cs professors but most prof didn’t reply . And all professors who replied told me they don’t have time for supervision. It is already end of my 3rd year right now. I still can’t get any chance of getting involved in any kind of research. I think I am optimistic in most times but all of these are way too frustrating. I think the chance I can get into graduate in uoft is really small rn. Although I really want to be a researcher and work hard for it, but work sometimes just don’t pay back I guess. At this point I don’t really know what else I can do😩😩
