Learning a language is unique to each person and exact timelines are therefore difficult to predict. We assume that you could be ready for your B1 exam within 6-12 months if you study at least 2 hours per day and take regular classes. 1 private lesson per week during your A1 studies and 3 private lessons during your A2 and B1 classes. Completing your B2 course should take another 4-6 months. Overall, it will depend on your dedication to your studies.
