Daily schedule of around an hour of work. It provided structure and encouraged regularity, while also allowing to catch up if life got in the way.

Using Circle platform in web version is pretty comfortable. Since I wasn't following the course regularly and did not participate in nor live events neither discussions. Yet, the part I already covered was enough to shine during a job interview and I got a new job!
