You don't need to understand anything when you can google the answer. I can get an A in the most advanced physics class in Stanford if you had the answer sheet to every test right next to me. That doesn't mean I understand it, it just means I have an A on the paper. Except this isn't about advanced physics, it's about basic education that children should know to exist as functioning human beings. You are putting way too much trust in a child to not do what they are being incentivized to do - cheat and get an A while putting in no effort.
