The bots have NO MERCY, once they teach you something you can not review them, the old lessons just gone. Then you only have one option to take the review test and again, they remind you nothing only tell you are wrong try again or quit completely. Also they are not very fair for beginer. You will have to try until you luck out bc you havent learned the words yet.
Sorry to hear you’re experiencing such a frustrating situation. Could you tell me which French course you are learning? And, are you talking about the Grammar bot – a text conversation kind of mode – or about the Grammar lessons – with multiple choice and tapping tests with a rule and tips?
