What's said upstairs makes sense. Generally speaking, from zero foundation to daf, it is suggested that 1200 hours is equal to 400 hours for primary school students+400 hours for intermediate students+400 hours for reinforcement.

If you study hard, 1000 can reach the level of German major. However, it is definitely not recommended to take the daf exam after 800 class hours.

Usually 400 full-time classes take two and a half months to three months, so 1200 class hours is about eight months. You can't walk faster unless you meet hard-working classmates.

TestDAF is a difficult test. Half of the undergraduate graduates majoring in German have some difficulties in the exam, especially in listening and speaking, which should not be underestimated.

If you are studying German full-time, 1200 class hours is recommended.

I hope I can help you.
