Aplicativo excelente, siga a ofensiva por ao menos 1 mês no modo insano e você se surpreendera!
If you want something you never had, you must do something you never did. And study in insane mode and engage, to more than 50 points per day for sure that in one month your progress will be very good indeed. Only one problem in putting this lofty goal. If the person is lazy, will not reach the goal and will discourage .... Good luck to all !!!
