I can't say the high school science classes I had were that great. For a large part, I actually sat out to the side, reading the textbooks and memorizing the hazardous interaction cards.
I'm pretty much almost entirely self-taught. chemistry, molecular biology, genetics to a certain extent, although I still need to build a lot of equipment before I can for instance, play around with transgenic organisms, toxicology, cognitive neuroscience, botany, mycology and natural history in general.
