Finally Finished My German Tree
It feels really good to finally finish and I'm posting this more or less to feel good about myself, but to also encourage anyone who really wants to learn that new language they've been working on, and even if you have hit points of low motivation, you can always come back and achieve your goals.
Well my mother is from Germany and I've visited many times in my life, so even though she did not teach me, I have had a lot of exposure to it all my life so starting to learn it in my personal life was not so hard to pick up on. Overall though I have been on Duolingo on and off for three years and one tip to retaining your words better is to definitely go back and review the lessons you've completed before. I would suggest about a week after you learn it.
