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 have the exact same problem, that's why I decided to NOT TO DO STRENGHTENING SKILLS, and just continue with my tree.
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.
