From freshman year, swimming lessons and final exams usually start after 8- 10. Physical education class can contact, but it won't be long, because there are too many people, and 1 hour at most is very good. In addition, the weather was not very warm at that time, sometimes I felt cold and didn't want to go into the water, so I missed another practice opportunity. However, you can also buy a swimming ticket and practice in the swimming pool when you are free.

Sophomore class is also in the second semester.

I hope it works for you.
