Juggling more than 2 languages at a time
I, for one, have 3 languages I'm currently working towards. They are completely different and share none of the same words. To be exact, they are Dutch, Spanish, and Greek.
Now, I have struggled to juggle all 3 languages. The thing is? You don't have to! There are a couple possible solutions to the "Juggling 2 or more languages at a time" problem. Here they are; I hope they help.
--> Solution 1 <-- You can just quit some languages! I know you can feel a bit defeated, but it can be helpful. When you feel less stressed, you can pick back up the languages.
If you're one who has 2 or more languages for business or school, then see the next tip.
--> Solution 2 <-- Have certain times in a day to practice each language. If you have an hour or even half an hour, you can fit about 3 or 4 lessons into about 45 minutes. If you aren't too concerned about one or two languages but still need to practice them, alternate those two each day. Have, say, Dutch on Monday, then Greek on Tuesday. If you have a major language you need to learn, practice that every day!
--> Solution 3 <-- If you rarely have time for Duolingo but still need to learn a language on the fly, then take the more weekend- based approach. Every weekend, take the time to study hard-core. For example, do Basics 1 through Possessives one weekend, Clothing through Adjectives 1, and so on. Make flashcards online or, if there's a deck, get Tinycards and use Duolingo's official deck for the language.
Currently I'm doing the FrenchByte way; you learn one language part-way, then another seems interesting, then you go back after a few weeks and try to manage them all at the same time. You fail, and concentrate on one. But then another one seems interesting and so you forget everything else and almost restart.
