I'd also love a poison oak visual quiz! Something I learned recently is that poison ivy isn't native to California—it's three variants either grow in Asia, the eastern US, or "not California." [1]
I'm a native Californian, have never knowingly seen poison ivy, only poison oak, and I still got 48/55. So it's still a helpful quiz IMO. Oak does tend to take slightly different form factors depending on its environment e.g. it can climb if it's around trees or stand independently if not; not sure if ivy does that.
