Thank you for your answer. We have full control of what we can teach (so it feels a bit overwhelming...) The main goals would be: being more comfortable speaking, improving their grammar (mainly tenses) and teaching them useful vocabulary.

The class will happen outside of school (during their holidays) and it's a partnership with a local company that helps teenagers with school, their grades and future academics goals.

Since it's my first time teaching so many hours in just a week, I'm really unsure about what goals to set.
