The one example I am willing to share is in high school economics class there was a stock market simulation. The person with the highest portfolio balance at the end of the year received a substantial amount of extra credit. First of all, this was 1999, and the market (tech-stocks) were in peak ridiculous bubble mode. The hack was that the software used to simulate trades and track portfolios used delayed quotes. So, I simply used real-time quotes looked for gains in a short period and bought held for a bit, then sold. Essentially I had a time machine. I think at the end of year my account had over $500 million in it. The teacher knew I was "cheating" but still gave me the extra credit along with another student who didn't "cheat". An extra perk is the cutest girls in that class constantly asked me how I had so much in my portfolio.
