We're sorry that your experience with Startup School last year wasn't great. That was not our intention, and hopefully you'll give us another shot.
You're definitely right that we were scrambling in the last minute to build software and adjust the program to better cater to the large number of companies in 2018.
As Kyle also mentioned in this thread, we spent a lot of time listening to the community and have made quite a few new changes and improvements for 2019 to better support the program at this scale and improve the experience for founders.
We'll also be taking Startup School on the road to meet SUS founders across the globe and will have YC alumni and partners participating in the Forum to help advise.
