IB

I am currentely a junior in high school. I am in the IB program but have had a very hard time with it, I didn’t want to be in it in the first place. I have very poor grades in the majority of my classes. I have mostly C’s and 1 D I think. I’m deciding whether or not I should even do IB next year. But I’m also thinking about my future. My mom says colleges don’t even look at grades when you have an IB diploma but I don’t believe that. I’m very scared that at this point I won’t get into college. What should I do?
