Translation of regulation in Spanish

So you have taken a German course in the Ghoete Institute. Well, I certainly learned something with you, and your German is already a lot better than last time. I think we really did it.
Take your time to answer me, do the vocabulary exercises and measure your progress! Your answers will be kept in the system itself. After that you can look at the statistics. That's pretty cool here.
If you are spell checking my letters, that would be great. I would then do the same with your letters. Can you please correct this email too? I thank you in advance for helping my Spanish.
