If you are applying for a diploma then around 60% is required in 12th, though there are some colleges which accept students with 55%. If you are applying for a Bachelors degree at a university, you need to have minimum 70% along with a SAT/ ACT score. For those who have not scored a minimum 70% but desire to apply for a Bachelors degree, they can do a 2 year Advanced diploma with a minimum GPA of 3 and then move on do the final years of the degree at a university where the college has a link.
