Literally beginner

Hallo Y'all. I'm Arabic mother language speaker and B2 English learner. My goal is to achieve B1 German language duo April or May 2026 because I'm applying for studying in Germany and settle there.

I'm looking forward asking you for materials that can help me making this goal real.

Any type of material is good (books, videos, channels or groups, anything)

I have no budget friends, so make sure it's for free.
