I don't like that I am unable to refresh my skills on a particular level in 3 to 5 sessions. The sentences are much harder and it takes much longer to complete. Is there any way to go back to the old way. There is a practice area but I have no control over the session I want to work on. Help, this is very frustrating to my learning.
Your problem is undoubtedly that you've pushed ahead down the tree far too fast without having fully learnt the early lessons. You're now finding all of the advanced lessons you've only taken to level 1 or 2 now featuring in earlier lessons making the sentences much more difficult to translate.
In other words, the system thinks you're at a much higher level than you actually are and is giving you correspondingly more difficult and complex sentences to translate.
You're at level 14, 6,673 xp, yet have completed 80% of your tree. You haven't practiced enough.
If I were you, I'd reset the tree and start again going more slowly this time.
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.
There is no way to go back to the old version (before crowns). I'm not sure what you mean when you say you want to "refresh my skills on a particular level in 3 to 5 sessions." You can pick which skill you want to review (for example, "Family") but you cannot select to review "Family" at "Crown level 2". They repeat enough that there is probably not too much difference, though. And if you get something wrong it will show that to you more often, so you get more chance to learn it.
