Translation of anstrengen

Grammar exercises give the teachers and the students different ideas. We discussed the need for exercises in my previous email, but unfortunately I did not receive any further feedback since then.
I will be creating an additional study with a student (his name is Juan), which may appear in local newspapers in the future (in English). However, this may take a couple of weeks too.
If you're still interested in our agreement, I will be glad to continue to correct your letters and essays. Write it in English, if you do not know a particular word and I'll translate it.
