Translation of ninth in Spanish

Hi,I'd like to ask you if it's possible for you to tell me briefly how to study here. I don't know that's why I'm not online most of the time. Thank you very much for choosing me as a friend. I hope our friendship can get better so we can practice.
I wish you would help me to improve my Spanish. I am studying law in Germany and I am trying to learn Spanish. I hope you can help me and I could help you to learn German. Have a great day.
I think I have to switch back to English. It will take me two years until I write an entire letter in German and I suppose I do not have the time for it. Does that mean that I am not serious about learning?
