How on earth do you define normal?
DD1 is NT but took her GCSE maths 18 months early and got an A. She struggled in other subjects but got enough points to go to uni. She's now been diagnosed with dyslexia and is getting the support she needs to do her course.
DD2 is 12, diagnosed with ASD two years ago. She is incredibly bright, top sets for every subject, one of the top two students in both science and French in her year. The only child to get a silver in the maths challenge in her school. She soaks up information like a sponge, remembers everything and is diligent with homework. Her social skills however are awful and that's what I and the school are working on most of the time.
A friend of mine has a son with ASD. Dreadful social skills, to the point of being rude but did his GCSE Maths age 12 and got an A*. He is incredibly intelligent and his school caters work to his abilities but again, the social side of things is more important to both his mum and the school so that's what they work on.
All children have a talent for something. Whether it's academic, artistic, sporty or something physical like taking apart something and putting it back together. Some are excellent communicators and do well in debates, others are very caring and empathetic and will do well in social situations.
I have yet to meet a child or adult that excels in all of these things.
