When I was a kid, I read college-level chemistry books throughly well before I took high school chemistry and ... they did me very little good.
I was only interested in exciting bits of the theories, not the slow slog of practical questions and as a result, was not really as far ahead of everyone else as I had thought.
Tell me, as you read the questions other people have posted, are you able to solve them easily?
And be specific, what lab practicals have you read about, that you want to do. Chemistry isn't entirely mixing stuff and watching what happens, there is a fair bit of theory at all times. I've bewildered people sometimes at work, I'd get an assignment, and I'd sit at my desk and start planning it out. Some people simply insist that they never have to do any sort of paperwork, which really isn't how the world works, in any discipline.
