how many exercises a day
I was wondering whether you Duo guys have ever calculated how many skills a day you need to practice in order to keep your whole language tree in a golden state.
If you click on "weekly" on the homepage, you will see a scheme with the days of the week. Each day will be filled up with coins the more you learn skill points. The coins will eventually reach a maximum level. I try to reach the maximum everyday, then i do a couple of timed pratice and then I stop :)
