Translation of audition in German

I have a few other short sentences by tomorrow. How can I pay for all these little translations? If I remember correctly I made also a small contribution through the channel last year... But I don't think you should charge for these ones.
I need to learn a lot of Spanish because I want to study at the university of Madrid. In Switzerland, I studied law, but after 2 years I have switched to medicine: to help people, rather than you know....
