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.
Thank you for your inquiry. Your Italian is very good. How long have you learned it? Last year I studied Spanish, which is very similar to my native Italian, but it also confuses you sometimes.
I have problems with adjectives, endings and articles. The grammar is so difficult. I am very happy to learn Spanish with you. What went wrong with the lessons? Thanks and best regards.
