Not moving to next level
I have turned all symbols gold but seem to be staying at same level
There is currently an A/B test in progress as part of which some users can see the information on the profile page (their own as well of others). Others just see the medal with the level. If the test results are favourable, the change will be rolled out to all users.
Edit: If you are not in the test group and wish to see the XP information, you can use Duocheck. Please check the discussion below for more details.
Try closing Duolingo, waiting a few minutes, and then opening it again. (Even better: close your browser AND Duolingo, wait, then reopen both). It will be interesting to see what level Duo shows you upon reopening and also, whether or not you'll be able to move up from there. I'd also post a note on the troubleshooting board. Edit: I see that you did post this on the Troubleshooting board.
As you seem to have covered the complete course, revision of the skills already completed can become a bit monotonous over time. You can try out at a few other options available.
- Immersion - In the immersion section, you translate Spanish documents to English. The articles can be on a variety of subjects and based on your interests you can take your pick. Also, you can add more articles if you come across something interesting in the public domain. The immersion practice helps in getting exposure to a wide gamut of vocabulary and sentence structures from real world documents.
- Reverse tree - For you the English for Spanish speakers will be the reverse tree. This is a good language immersion experience as you now get to experience the website from the perspective of a native Spanish speaker. You just need to keep in mind that the objective here isn't learning English, so testing out quickly doesn't help much. Instead, steadily progressing through the tree is more useful. The regular Spanish sentences even in early lessons may use complex grammar or sentence structures as it caters to native Spanish speakers. The sentence discussions will give you a glimpse into the nuances of discussions, arguments, debates of native speakers.
