Volunteering - time and effort well spent
You will already know that in the sixth form you are not in lessons all day every day, so why not use your time for hugely rewarding experiences?
Being linked so closely to South Hunsley Secondary School presents lots of opportunities for you to help out teachers and younger students. In any course you study you can help Year 7 students in that subject, acting as a Teaching Assistant or general classroom support. Alternatively, you could choose to be a Reading Mentor, working closely with a Year 7 student during morning registration to help improve their reading skills.
If you're a good listener and someone your friends turn to for advice, Peer Mentoring could be a useful way for you to spend some of your free time. The scheme runs in order to give students from lower down the school the chance to talk through their problems with older students who can empathise with what they are going through - friendship problems or difficulty with homework, for example. Informal drop ins are arranged on a lunch time or you could meet one to one. Either way it can be a hugely rewarding experience.
