Your post really resonated with me. It reminded me of a conversation my oldest son and I had with a woman at church when he was a high school sr.
She asked him if he had decided on a school and major. He told her yes and that he planned on majoring in chemE and where. She looked him in the eye and told him that he needed to plan on a different major b/c her valedictorian 36 ACT ds had been a chemE major there and couldn’t manage the work and was now a psy major.
My ds was definitely not a “36 on the ACT” student. He proceeded to graduate with honors with his chemE degree. While an UG, he was invited by profs at that U to participate on their research projects and then received great LOR from them.
