I’m sharing an article through the National Center for Learning Disabilities on being tested for a learning disability in adulthood: http://www.ncld.org/adults-learning-disabilities/do-i-have-ld/being-tested-ld-adulthood
If you suspect you have a learning disability, there is no time limit on finding out. The results may give you the answers you’ve been looking for, especially when you were a student in middle school and high school.
It’s never too late!
