...computer programming? In second grade I had poor reading comprehension, would this effect me doing VBA and Access, behind the computer?

not likely
how are you at solving word problems?
Good math scores is a good indicator that one may do well in programming - not because there's a lot of math - but because of the 'way of thinking' - some get it but some ought to change their majors.
I don't know how you did in math - you answer that to yourself.
