Verb conjugation of "ridicule" in English

I have been living in Holland for the last 14 years and I know the mentality very well. Holland is a small country, everybody knows everybody, so if we want to succeed, we must seize the opportunity.
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 attended a Spanish course in Malaga, but I need more practice and speak more often (and write of course). Here in Germany it is a bit difficult to learn Spanish because we do not have the chance to practice.
