If you get all C's can you get into uni?

if u get Bs & 2 A, your OP is definitely within 10-15. it depends on the uni and their cut off level. some would be willing to take 17 or 16. so no worries. With Cs u can still make it around 15. your dad should have confidence in u. but dont be discouraged. look at www.virtuesproject.com - its qualities will boost your confidence and capacity. so pl dont give up but persevere and prove dad wrong. all the best
