How is the fastest way to earn points?
I know this sounds kind of cheap, but how do you get points fastest?
Oh, damn. I had studied SQL more than 3 years ago. I can't remember a thing. I was about 14.
How much money would he accept as contribution if i ask him to choose that the german specialists make a review on the german section of Duolingo's languages?
If you use your lingots to purchase a "Timed Practice," you receive 20 xp (if you answer all the questions correctly) instead of 10 xp for that exercise.
The "Timed Practice," once purchased, can be used repeatedly. It's best used for units where you have strong knowledge, as time can actually run out (unlike the traditional strengthening exercises.)
The better thing to do if you want to get more skill points is doing it by learning more faster.
