I got 5 wrong...
I couldn't count to 8 on my fingers properly and entered the wrong element on one question, I also didn't know the cloud thing, I have learned what Palladium is for, I learned that Mars has less gravity than I thought it did, and I had forgotten what the h constant was for.
Also, is it sad that I learned only maybe half of this in school? And only 34% in high school? (For the school system, that is, not for me.)
