Frequently asked Questions

Got questions? We've got answers

It's completely up to you. The time it will take you to be "job ready" will depend on how much you already know, how often you study, and how long you study for. That said, the backend career path takes many people about 12 months.


Absolutely! If you built it, use it. You'll build several personal projects while completing our curriculum, and our final course about finding jobs will show you how to construct a job-ready portfolio.


We're not a $10,000 bootcamp.

We're not a $50,000 university degree.

We are a self-paced, gamified online learning platform for back-end web development. You can learn with us for the price of a gym membership.


You can read all about our methodology here. In a nutshell, we're laser focused on teaching backend-development, which is somewhat of a rarity in online learning. We're also focused on solving what we believe is the hardest problem with online learning: boredom.

If you prefer coding rather than watching, and your struggle with online learning is staying motivated and engaged, we think you'll like learning with us.


Yes! It's free to create an account and start learning. You'll get all the immersive and interactive features for free for a few chapters. After that, if you still haven't paid for a membership, you'll be in read-only (content only) mode.
