Verb conjugation of "anstreichen" in German

It all depends on the language that you want to learn. For German it would be best to go to Berlin, as the pronunciation is classic there. Imagine going to Switzerland where they speak a different language.
The conjugations of verbs are the biggest problem for me. I have never studied Spanish in school, but visited evening classes instead. This year I want to take a full Spanish course.
I live right next to Montpellier, in a small town near the coast, in France. I have no children and I'm learning Spanish because I like foreign languages. I learn vocabulary and grammar. Vocabulix helps me a lot.
