Starting my first language class since June

There are two ways of learning a language:
1. Memorizing grammar rules and vocabulary
2. Practicing it in many real life situations
The first gives you a rather passive knowledge, but is good for exams. The second gives you a feeling for how to get your message across, but doesn't give you perfect German.
It is of course best to use both methods to get good language skills, but different people have different learning abilities and fluency expectations and thus need them in different quantities for best results.
If you are better with the second method, then stop focusing on exams and start mingling with Germans and talking as much as possible!

Hi,
I came to Germany 3 years ago. I can give you some suggestions besides the german class.
1. Do not hurry. Try to find ur pace that suits you.
2. Do not be afraid to make mistakes.
3. Watch the german news and quiz shows.
4. Read a german paper
5. Try not to speak german whilst translating from your mother language at the same time.

Greets,

Thank you, I'll make sure to make use of your information, I'll try harder on making a friend here, so I have someone to speak in German with.

I'll do that! Yeah, I tend to stress myself out a lot, because I need to be at least C1 in the next 2 years and I'm worried I won't make it. I'll start doing the things you mentioned.
