my next language
I am learning Spanish and French. what should I learn
You should keep with French and Spanish, or pick just one. I don't think you're far enough in your language journey to do another language. I recommend waiting until you're level 9-ish. I didn't start my second language on Duolingo until I was like level 12, and I still have difficulties sometimes.
Keep learning French and Spanish, or else it will get hard to keep up with lots of languages at once and you'll lose interest. However, I recommend you get to about Level 10 on French and Level 7 on Spanish before you start something like Portuguese, because of Portugal being left of Spain, and Brazil surrounded by South America.
