Hi Rita,
Great to find that you are enjoying this forum. I've been studying in Germany for my bachelor degree and right now i've started master degree for Databases and Management which is in the field of Computer Sciences. If you would take the time to make a simple search on Google you could find interesting information about things that you need to study in Germany. But sometimes the language may be the barrier so i made a quick search and here i found this site which is providing a great guide for foreign students who want to study in Germany: http://www.mawista.com/en/study-in-germany/ or you can find more information just by doing a search in Google: Study in Germany or Student Guides to study in Germany or other queries like that.
Hope that i could help you a little.
