German GCSE Grammar RulesWatch
If you studied German GCSE, what are the main grammar rules you need to learn, because I find it very all complicated
Hope that helped.
The main grammar rules that a lot of people I know struggled with was clauses and where verbs are supposed to go in the sentence. Basic things like verb second, second verbs at the end of clauses and subordinate clauses are extremely important. Is there anything specifically you're struggling with?
In addition to this I'd try and absorb yourself in german media, listening to people speak a language is extremely helpful in understanding how it works and you'll find it comes more naturally too.
Yes, though I'd start with reading or only watching educational German media to start with (like Hallo aus Berlin) because fluent Germans might speak a bit too fast for you to follow.
