How do you use a tree shortcut?
Does it affect my lingots or my streak? Please tell me. :D
Their are shortcuts that cost no lingots. It should be at the end of 3-6 lessons , says "shortcut". If you pass the test showing duolingo you know everything in that category, then you can move on to the next one.
I didn't worry about lingots nor streak when I tested out of skills, although there is a note in the store about lingots not being awarded ... please look it up for the exact text.
What I noticed is that a lot less vocabulary was stored on my words tab and I consider this as a huge disadvantage of the level test at the beginning, the tree shortcuts and test out option on skills.
