What does Crown Level refer to ?
For an individual who has reached level 25 and 24 in spanish from English and French, the crown system is absolutely useless! I was expecting that the higher you go in a crwon it will get more difficult.. Not the case.. I did Animals up to level 5 and It was always the same between the levels... In fact besides Elephants, monkeys, horse, lion, bull, cat, dog, crab, rabbit, penguin, fish, birds and few others more, the difficulty has not changed... It gets boring to use the verbs comer and beber, and always drinking water or milk....As a feedback Duolingo needs to expend the vocabulary when reaching higher levels within a crown. This would make it more interesting and more challenging... I guess I will stay with the "revise " option and forget about the individual Crowns.....A thumb down on this one Duolingo....
