"development, drilling 11+ papers isn't going to make someone genuinely more intelligent."
Yes but it will make intelligent kids higher chance to go through 11+ exam.
However, its not reasonable to shout down everyone who suggests their experience isn't hours of tutoring a day. Everyone should be able to speak about their approach and how it worked.
Yes, you probably right, 10-20 mins per day is enough for most of the kids. 🤐
