It’s sad to hear that people feel guilty when they get something right. It all stems from a lack of self-confidence and limiting beliefs that people that are more popular and faster at math should get the correct answers. We’re all great at some things and horrible at others, and oftentimes, it takes us longer to accomplish something than others.
That’s what makes people so special, their uniqueness. These confidence people could be taken down a notch or two, and should even praise this guy for answering difficult math questions correctly (via Constative).
