Confused? You already “joined” the university so you were admitted? What program? If for undergrad you must meet requirements. This is the same for all universities. So if you don’t then you can’t attend university.
Once you have admission, apply for a study permit. You need to pay first year tuition and show that you can afford the program so a minium of $10k. You will want more if a 4 year undergrad program. You need to show how the program will advance your education and give you career opportunities in your home country.
So you are applying for admission to a 4 year degree? You will want to show that you can afford tuition for 4 years. If undergrad and you have high school diploma then you need to find out if you are eligible for admissions. Don't know what a 8th univeristy is.
