I am looking to apply for study visa in Canada.I got admission in bachelor of science degree in memorial university of Newfoundland but the issue is that my marks in Maths were not good they were only 33.My overall percent in 12th is 62 percent and in 10th 72 percent.I have paid the university fees but I am really worried at this point about whether applying for the visa is worth it or not.I feel like I should do my bachelors in India and after improving my grades then I should apply.If My student visa gets rejected,Will it effect my visa application to other countries in future?
