I completed the Full Stack Certification today! What started on April 9, 2019 and completed 226 days later on November 21, 2019 is now complete. Although I had some prior coding experience, I believe that the curriculum was conducive to learning and that I improved my skill. I committed an hour or two per day - including weekends and holidays.
The API and Quality Lessons had some defects as well as the FCC site itself but the community and the Read-Search-Ask Method were very useful along the journey.
Thanks @QuincyLarson, all of the volunteers and the entire Free Code Camp Community!
