If you like this method of learning or of teaching, check out Oppia, open source software for building things like this: https://github.com/oppia/oppia

The public site with existing lessons is here: https://www.oppia.org/library

I'm not sure how socratease.in compares. But Oppia has some cool things like being able to set questions which require more than just multiple choice, e.g. requiring you to put a musical note in the right place on a stave.

Hi Rahim, thanks a lot for the reference. I did check them out, both the demo video and a few libraries. You are right that the basic premise is the same. And, yes, they allow for a much more customisable flow. Lots to learn from them!

The Oppia code base is licensed under Apache License 2.0 so you could even use that as a base if it covers everything you have so far.

One difference I see is that Oppia seems to be making AJAX calls (am not familiar with Angular, so, maybe I am wrong). Whereas, I deliberately chose the quiz flow to be one that goes to a different URL as you progress. But, yes, will take a look at the backend and DB and see how things are stored and processed.

I learnt just enough web development to be able to build this. So, it will take me a little bit of time to understand code written by a Google team :)

"I learnt just enough web development to be able to build this."

Congrats! Seriously, this is the best way to learn. We're all on the same journey :)

EDIT: Yes, Oppia doesn't appear to update the URL after each step. So if you refresh the page you're back at the start of the lesson. (They didn't have to do it that way, though: http://www.codemag.com/article/1301091)
