My skills aren't strengthening no matter how hard I try
I do my Duolingo on a laptop and I have strengthened irregular plurals 3 times and it had a 3/5 strength when I started and now it has 1/5. I barely peeked. What did I do wrong?
I'd recommend the skill strength viewer. At the moment, it's still working for me but I've heard that will change. I do strengthening and/or refresh the lessons based on the percentage shown in the skill strength viewer rather than the number of bars/gilding. If something is 4 bars but 50-something percent, I'm more likely to work on that rather than a skill that is 3 bars but over 99%. I'll also work on skills that have a lower percentage even after getting to 5 bars/gold.
