Do you think a person with a 6 grade reading comprehension level should attend college?

I am 25 years of age and am thinking about attending college to become a Registered Nurse. The only problem is that I am not very well educated at all. I have a 6 grade reading comprehension level. i really can't understand much of what I read. i am not the smartest person at all. I have a learning disability and I want to overcome it soon. Based on what I told you about myself, do you really think that college is for a person like me?
