I have been in 9th grade 3 times and cannot pass

I talked to a mom last week.  She has a son who has been in the 9th grade three times.  His sister, who is grown, thinks he may have dyslexia.  Mom says the school told her he will not pass if she puts him in school this year.  Will mom bring him to see if my tutoring will help him?  Has the son given up on schooling and will he even come see if my tutoring will help him?  I do not know.
