I taught both of my sons to read at home using basic phonics. The two of them had strikingly different learning styles but it was not difficult for either one of them. When he finally entered the public classroom at Grade 10, one thing my older boy said he didn’t like about school was that it took too much time away from his reading.
Yes, in Jr High, the teacher caught me reading a book behind the textbook once and called in my mother, who asked the teacher to give me a quick test on the textbook. I was able to answer every question!
