Did you ever wonder how soon you will get your golden owl if you keep learning at your current pace?
You are making 9.61 lessons per day on average and you still have to finish 428 lessons to finally get your shiny English golden owl, you would be there by 2022-09-28 if you keep doing L1 lessons at this pace.
Please, keep in mind that 4.76% of your lessons were some extra activity like stories or timed practice sessions and while these don't take you any closer to your golden owl, they actually give you some more experience.
It's a good thing... )
Keep going! =)
