I am not pinpointing anyone, but just to share my experience and raise my voice as well. I have noticed lot of people doing this lately. Even I met some senior people on my way to IELTS. They use to mock you and even make videos on you, stressing you out and somewhat setting example out of you to make people subscribe their channels and services (this seems to be the only reason). Similarly, I came across some people here as well who, rather than answering your query, are more interested in suggesting you "don't come to Canada" (it's like they have written a signature line and pasting to all of their replies). Do you really think, people are fool and can not take informed decision. The only reason they are here is to seek guidance and help others. and instead of making any positive contribution, you are pushing them down. I think these are the challenges which concrete your resolve. So big thumbs up for the one who are still pushing towards their goals. Persistence is the key. These naysayers would count to nothing.
