I will gladly help you and so will everyone else when you get stuck or something in particular doesn’t make sense to you.
But you need to be specific, you can’t just ask “How do I make a question and answer app?” there a many different of ways of doing it.
Once you have mastered the basics first, and know how to use composer I recommend you read up on using data bases, you will definitely need this knowledge, also look for Rob Miracle’s “loadsave.lua” API, that’s what I use, it took me days to get working but I kept at it until it worked how I wanted it to.
I started learning Corona by following tutorials and putting them into practice, I spent 2 months learning nothing about the app I wanted to make but it was 2 months well spent.
Get a large notepad and write everything down, I’m on my third large notepad, it’s always in front of me.
Make a folder on your computer to store useful code snippets in too.
If you want to friend me and when you need advice I’ll gladly point you in the right direction, I am making the same thing you want to make after all but I’m 7 months ahead of you and nearly finished so I should be the perfect person to ask.
Good luck and stick with it, you’ll be very glad you did.
