General confusion is why I'm doing just the one. Did 6 simultaneously once though, so mixed up but fun! I loved Finnish, and Finland, and Finns! Maybe start off with foreign borrowed words to make it less intimidating? And about that difficulty, man, if toddlers can do it, we can too! <3
I found lots of great info on this and many other words, as well as a bunch of help on the website. Go to Duolingo.com and just sign in like the app. It has all my progress right there. You can work right from your desktop, too. They have grammar guides, verb conjugation, pronunciation guides & more.
