Quiz Factory

Question

How do you get to it and what is it?

Answer 1

I believe the Quiz Factory has been disabled for all android users. So there’s currently no way to get to it. It basically lets you create questions that are then by some process accepted or not. If they are accepted, they will end up in the sololearn challenges as a possible question

Quiz Factory is still alive. To access it, tap on "house" icon at the bottom bar and then tap on 3 lines at the top left corner of the screen (or swipe in right direction) there you will find quiz Factory, where you can create your own questions for challenges and rate others submissions. I think "Lesson Factory" is gone.
