(I hadn't heard the term "grammar school", I looked it up and it means a separate school for the academically gifted) In my personal experience, I was not in a grammar school but within my school I had half a day of separate "advanced" classes of STEM subjects. I felt like they helped a lot, I had more perspective and much higher quality of learning from my peers, not just about the subjects but also on strategies to learn quicker and most importantly in finding the joy in the beauty of math and sciences. On the other hand, I could see increased stress in myself and some of my peers when we suddenly weren't the best in our classroom but just average -- which is an important lesson itself for sure, but the teenage brain reacts weirdly to that stress. Overall, though, those classes highly accelerated my learning, made me used to solving many quizzes quickly, and I made some great friends there. I wonder why this seems to have failed in England?
