I purchased the System Design practice and I think it's amazing. It's the best way I've practiced system design so far. I have both versions of grokking, system design school, alex xu books, and the course from SD interview channel. The feedback given gamifies the process and makes it fun.

This tool is insane. I have been racking my brains trying to study for my system design interview on my own and trying to determine where/why my solution is meeting/missing the bar. I feel my progress in solving system design questions just 10x'd with this tool. Thanks so much for building it!
