I've always liked math (though 'showing my work' took almost all of the fun out of it later on), and I was pretty good at it, up until freshman year (9th grade 'round these parts) in high school. After that, I started an independant learning program, where I basically made my own projects (based on all sorts of guidelines, like what sort of credit I needed at any given time, and certain numbers of hours required per credit). Since I could choose my own projects, I neglected math for a year. Then, I struggled with it for another year, and I'm only now relearning everything as a senior.
Fortunately, I'm also in a program this year where I can get some of my high school credits by taking classes at a community college, at the state's expense. This quarter, I've been in an astronomy class, in which I've been able to get 90% of the algebra I forgot back into working order...
So, I guess by a lot of definitions, I'd be a math/science person, but I also spend a lot of my time on art (drawing and photoshop) and writing. As far as multiple intelligences go, I think I got a pretty decent point-buy, but Music has to be my dump stat. Sure, I like listening to some music, and I learned to play the recorder in 4th grade, like everybody else, but I just don't have any interest in playing any instruments, composing any lyrics (beyond guileful parodies), or even listening to the stuff on the radio.
Wait, what was the topic? <checks thread title>
Oh....uh....hrm...because it wasn't ever taught to them in a way that meshes with the way their mind works?
