I'm going to be brutally honest with you, your grades are good and you need to keep it up if you're trying to apply to canada or the usa having extra curricular activities on your resume will help you alot but at the end if its usa or Canada you'll always have to pay a certain amount. Let's say they give you 25000 dollars, most universities total cost is from 30-70k so there will be some amount you'll need to pay, and you can apply to us and some canadian universities through the common app(its a website) and as for the rest of the canadian universities you will need to apply directly through their websites and if you get accepted they will show you your next steps through email or their portal, European schools do have scholarships aswell including full so you'll need to apply depending on the country. Search for it online and I wish you the best of luck!!
