You can try a deck, answer questions, get a score, see what topics you’re weak in, and use an AI coach to understand mistakes. I’m not trying to sell anything right now — I just need honest feedback before I show it to more people. Main things I want feedback on: Is the app easy to understand? Does anything look b

At the same time, I've been getting frustrated that my intermediate/advanced math skills have atrophied, and becoming more senior in my career (plus AI...) has caused my coding skills to atrophy even further. Realistically I'm not going to force myself to do math or coding exercises aft
