I have to say, one more time, that I've been positively surprised by the quality of the YC Startup School course - and my expectation wasn't low.
When I started the course, in August, I published that my plan was to weekly write about my experience and the course material. I asked authorization to Y Combinator to do that and it was granted.
Due to the quantity of Startup School material - which, taken seriously, requests a reasonable study time - and also my personal need to focus on the work I'm doing at Nave, I wasn't able to weekly publish the course material and my experience.
Now the course is ending, I decided to publish a digest of all the Startup School 2018 material. I took the decision to cut off all my personal notes of each lecture and additional materials - because I believe who's interested should study the course content and build his/her own comprehension of the addressed subjects, instead of getting ready answers.
Here's the YC Startup School 2018 full course material.
Wish you a good study!
