@jm208158 My son sent in the Act and did not send subject tests. He also did not do the optional writing. He got in ED. I believe you need to send all subject tests and one he did not do well in so he didn’t send. So I think it depends on how well you did. If it won’t add to your application I would not send unless you have to with the sat. He did well on two but one physics he did not because his teacher did not teach electricity and magnetism.
