Oh, I see. I was so busy concentrating on the letter I didn't notice those. Yes, you're right, that won't work. By "overview of grades of study" do you mean what we call a transcript? It shows all the courses you took and the grades you made for each year you were in college or university. If that's it I would write "XXX University transcript."

I'm not sure what "testimony of electrical assistant" is, either. Is this what we call a "letter of recommendation"---a letter from someone you worked for saying what a great guy you are? In that case I would write, "Letter of recommendation, XXX."
