Hello Madina!
Unfortunately, I cannot give you a clear answer to your question, as classes begin at different times depending on your schedule. I can tell you, however, that the earliest your lesson can start is at 8:30 AM and lessons end at 6 PM at the latest, for as far as I know. I personally have never had a lesson end later than 5:15 PM, though. Do not worry, you will not have lessons between these times every day (I do not have days as long as that), and at least one day plus one morning/afternoon per week are scheduled for your business case. So, overall, there is still enough time to travel to and from school and to spend on other things.
Hope this helps!
