Question for those with teen aged kids - regarding tutoring (long story)

[KitchenWitch]

My son, who is very bright, and does very well on standardized tests (90+ percentile), struggles a little bit academically, in part due to lack of organization, and in part due to lack of interest.

Long story short, I took him to one of those "learning centers" to have him assessed, and we had the meeting today to go over the scores. They wanted me to sign up for 200 hours of tutoring at a pricetag of nearly $7,000. Needless to say, I did not sign him up, and let the woman there know that it was highway robbery.

He showed weaknesses (according to this woman) in his reading speed, his reading comprehension, and his basic math skills (without a calculator, which they have been able to use since 5th grade). In addition, I know for a fact that he needs to learn basic study skills. I am meeting with his high school counselor on Monday for another reason, and am going to ask her what resources are available to me through the school system, and what resources outside she might recommend.

Are there any strategies other parents have used to deal with bright children who are academic underachievers?
