Translation of mediocrity in Spanish

I'm Ricky. I am learning English at school here in Switzerland and at the same time I am learning Italian. You writing skills are very good. Where did you go on your last vacation? See you next week.
I would also need to know whether pricing can be different, because otherwise that amount would be too high. Some of the translations are not accurate at all and would also need corrections so that the dictionary displays only correct words.
I hope that we can teach each other a few things. I work as a nurse here in Boston, and it gives me a lot of joy and comfort because I like to help other people. It is a job that takes a lot of effort.
