How does the badges and rankings work

I've never been clean on this. Can someone explain it to me>

I don't fully understand everything myself. But if you look at the "task?" bar, under help, is FAQ's that helped me tremendously. There is a bunch of info there.

Thank you @Myr. I had looked for that in Q&A. But not being the brightest, I couldn't find the info. Again, thank you!
