Nothing in this change says that a kid like you wouldn't be able to get into Harvard under new policy. They won't REQUIRE SAT scores, they aren't saying they won't use them if you submit them.
right, harvard reserves the right to admit someone who may potentially have really bad SAT scores. But that's fine, if admission officers see that person as Harvard material, why shouldn't they? Most candidates will still submit ACT/SAT scores, and average ACT/SAT score of the incoming class will likely still be high.
