I am very sorry that a cannot see animore, which subjects or grammar I have to strengthen. Why is that?
You can see the number of "crowns" you have acquired for each skill. I would focus on those skills that have relatively few crowns, and on those that I find particularly interesting.
I think I've read somewhere that the "Practice" button takes into account what you've studied, and what mistakes you've made, but I'm not sure.
Here's the FAQ thread on the crowns system, which I find very helpful: https://www.duolingo.com/comment/26739837

Hi, this is the Spanish forum, for getting help with Spanish grammar, vocabulary, resources, etc. Could you please edit your original post and use the drop-down list at top left to change the topic from "Spanish" to "Troubleshooting"? That way it won't clutter up the Spanish forum, and the answers you get might help others who look in Troubleshooting for information on how Duolingo works.
