I want to learn german as fast as possible
Get private lessons.I know a guy that learned perfect german in one month.He went on private lessons every day and quit his job to stay home and practice.
u know , I should study hard for entrance exam so I don't have much time . I started learning german 1 month ago n' now I can get A1 degree but it's not enough for me n' thank u for your guides ;)
Don't rush yourself, or you won't learn it. Take your time and take things in slowly but efficiently.
