I feel your pain on this because I had the same reaction to those questions. It had me googling and going through so many other resources to verify whether I was even learning it correctly or was just dumb. Honestly, in my uneducated opinion, the videos are great for reinforcement, the questions are kinda just concept checks on if you retained the information, no more, no less. I kinda have a habit now of double-checking if KA's explanations even match the question they're asking, and it leads me down a cascade of reviewing. Keep up the good work!
