The better the test scores, the better the college placement. Remember that college placement is based on performance and nor necessarily on perceived potential. Good performance helps a post-secondary institution predict success on their campus. As a parent, one should do everything they can to facilitate the academic progress of their ADHD student. Good planning begins early, and early intervention and preparation set the ground work for college success.
College is nor the place where success happens spontaneously.
In point of fact, problems exacerbate on a campus where there is a lot of freedom and little external control. Success is the reward that comes with early planning and good preparation.
