Have a look at the Help section or look into Academy (both at the top right of the screen). How you revise depends on your preferences. The LingQ advice tends to be: Listen before your read. Listen as often as you need to feel comfortable with a lesson, listen and read along with the audio, again as often as you need to feel comfortable with a lesson. Listen without the text again. Remember you do not have to know everything word in a lesson. Use texts that interest you. In the next lesson you will come across familiar and new words. Start the same cycle: Listen, Listen and Read, Listen. Review your flashcards if you work with flashcards. Do some of the other exercises offered. Move on.
Of course, one time is not always enough even for your mother language to understand everything well. You have to repeat every lesson maybe 5-10 times to keep in your memory main words and structures of a new language.
If you are a beginner, not one time a day, but 5 times a day!..
If you are on a level Low Intermediate or higher, you can listen to the same podcast or two podcasts 2 times a day, maybe one lesson a bit more difficult and another a bit easier.
I do that in english (but i have a intermediate level), but i did two listen in Japanese while i’m beginner. That’s the problem! Thank you for your help, now i know my mistake :3
