Now I no longer need with the book behind my son chase after and retrieve annoying vocabulary. The program queries vocabulary and automatically sorts them into different phases. If one has a vocabulary correctly it comes to the next stage and is interrogated by a committed timetable again. This period shall be extended depending on the phase. Is it in. 6 Phase arrived (think 6 months) it is in Langzeitgedächnis. The program also pays attention to spelling, even whole sentences are queried. Accuracy can adjust it and it can also buy several "students" in each learn their user accounts. Warning: This is only the program that respective textbook be purchased separately (different from school to school), so the software needs (10). For us it is now relaxed with learning English ahead and my son has already improved in the notes. In addition, learn the PC for him a little cooler than boring book and dam ..... en he can not.
