Both my sister and I were tagged as "gifted" when we were kids. I remember a child psychologist (I think that's who it was) coming to our house one night and doing a series of tests on us both to test IQ and the like. My sister skipped a grade and I was placed into a gifted kids program when I was in year 2. I was always selected for the maths/English/science Olympiads and when I started in year 8 was selected for a place in an advanced maths class with about 5-6 other kids. Our downfall was definitely schooling. In primary school, my sister was bored a lot of the time and as just seen as being disruptive/naughty. Despite mum and dad complaining to the school that they weren't challenging her enough they just waved it off. When I got to high school I was friends with the "smart kids" (inc one who was the youngest person to ever join Mensa...) but was always made to feel like I wasn't smart enough. It all came to head in year 10 when a maths teacher decided to show us about 5 different ways to solve equations, but we were only allowed to use the "proper" way on exams. I kinda gave up at that point.
I had a friend whose parents were always boasting about how great she was, how smart, talented, gifted, intellectual etc etc and I think that just annoyed my parents so they stopped talking about us with them as all of that was their own opinion - she has never been tested by anyone for IQ and they made mum and dad feel like we had to "compete" for who was most gifted. The day this friend found out I had also won a half academic scholarship for yrs 11-12 was priceless (she had also won a half scholarship). It was her total disbelief that I was smart enough that made me feel good. I got sick of the comparisons from her so I just stopped trying. Even to this day (10+years after leaving school) mum and dad still see her folks socially and get told about how fantastic she is. They just don't bother, because they know that I'm actually in a better job, earning more money doing something that I love, in a stable loving relationship and actually enjoying my life.
I excel more when it comes to patterns and logical thinking. Working out/looking for patterns is numbers is something I seem to do subconsciously. I devoured logic puzzles etc when I was younger, and faced with an issue I was usually able to solve it. Once I got locked out of the house after school as dad had taken the front door key off my keyring to get it cut. I still managed to get inside by taking off the fly screen to my bedroom window, reaching in to get the window key that was on a hook on the wall, then using my window key to fit inside the lock on the garage door, then jiggling the door handle of the house. Mum couldn't believe it. I was only in yr 8 at the time. Either that or she was worried I was going to have a career as a house burglar!
I think the trouble with the "gifted" tag is there isn't really enough in the schools to test or challenge kids these days, and kids aren't allowed to reach their full potential. I babysat for a brother and sister when I was about 18/19 and the little girl was very bright and clever. When she started prep she was streaks ahead of the other kids in her class/grade. She was at a level where she was actually doing her older brothers work with/for him (he was in yr 2). There were discussions with the school about putting her up a grade, possibly even 2 and her parents were all for it, but the school in the end said no as they didn't want to inhibit the brothers learning by having his younger sister in the same grade as him. I think the following year they ended up putting her up a grade because she was just so far advanced over the other kids in her class it was so totally wrong to keep her where she was.
