It was suggested to us at the time to get a head start on test scores. My Son took his early fall of Junior year for that purpose. I am confident it helped him with his early offers from HAs. He had a couple of HA teammates that tested way early and landed Ivy offers. How did they get an Ivy offer do you ask? These were border line D1 baseball players who had almost perfect test scores and grades that provided flexibility to Academic Index criteria that some HA schools have to deal with. The earlier a HA school could land one the sooner they can offer a much better player with lower grades and scores.
