If you want to improve and skip sections, get a tutor!
I’ve had a Spanish teacher once a week for around 8 months now, and i’ve noticed the lessons have been becoming easier for me on Duolingo, and instead of doing a few lessons each day, i kept just skipping units and doing their tests.
I noticed they were still really easy. So i tried to jump a whole section to test my Spanish, and managed to skip over 30 units…
I recommend it so much. Don’t get me wrong, I know repetition is key, but sometimes Duolingo can be just a bit too repetition to where you don’t learn much anymore.
