What kind of learning disability might I have?

Do you really need to know what your LD is? Honestly! You are in uni and you are making good grades. Most of your high school friends wouldn't have got that far without having LD's. I am sure if you desperately needed to know you could talk with a professional on campus or ask your mother to be honest about why you needed extra help in school.Personally I wouldn't give it another thought if you are coping as well as you sound you are. I hope you achieve all your goals.
