Some tips on how to keep you streak, daily goal, etc.
Try and tie studying to a routine you already have. So for example if you take the bus to school use that time to meet your daily goal, or if you have a TV show you like make sure you study first and then watch it as a reward.
Who cares about streaks etc ? I had one of a about 1.5 years and then my husband's spinal tumour recurred for the 3rd time, requiring hospitalisation for 4 weeks and 2 (unsuccessful) surgeries. Obviously, I lost my streak but I found the release from being tied to it very liberating.
Just do regular practise (here or elsewhere) when you can and you will advance in the language.
I suggest at least fifteen minutes a day on Duolingo. And if you do that you should be able to keep your daily goal and earn lingots.
You are lucky to be studying another language while you are young. It is much harder to learn when you are older, our brains do not work so good. In most other countries people speak at least 2 languages.
It may still be hard, but your brain is more elastic and learns easier than older people. Also, you have time on your side. If you study 15 minutes of language every day, you could be multilingual by the time you are an adult. I wish I had started earlier.
I feel very lucky to be currently learning French in school and to have the opportunity to learn another language so young. At this point, it's impossible for my mind to work like that of one who is bilingual, but it is still better than what it would be if I were to try to learn as an adult. I don't know if you come on here because your school requires it, but I know that I come here on my own for extra practice. Either way, I hope you keep it up!
Strengthen the skills you have already done. Ask someone to quiz you on certain words.
set the XP goal to 1XP, like if you forget to practice and remember late you only have to get 1 answer correct on the timed practice to extend your streak
also always have the streak freeze bought
