Verb conjugation of "verhören" in German

My boss offered it to me, so that a few more people at work will have a good level of English and now I really have to kick my own ass (I've started last year and it's not going very well).
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.
What kind of movies do you prefer? Anyway, should I write you to your email, vocabulix inbox, regular mail? I'm living in the North of the U.S., near the Canadian border. Have you ever been here?
