Translation of Oma

I need to write you one more sentence. This is what my teacher told me and the German language is so difficult. So please, as a last favor, would you please write the sentence for me in German?
After our system update, lessons will be saved for 30 minutes automatically, if you want to save them permanently, you need to press the 'save lesson' button. It than works the same basically.
Is there a way that I could test your Spanish and German lessons? Quality is very important to me. Can you send me a lesson electronically (by email or word)? Maybe you have your lesson ready.
