activities outside school

The activities I have outside school are swimming, tuition and basketball.I usually play basketball and swim everyday.I spend about 1 hour on each activity.My parents think if I have tuition,it will improve my studies and having sport will make me stronger and taller.I think this activities are very useful as I really get stronger and taller and also make my learning better.I think my schoolwork and my other outside activities does not clash together.I do not feel stressed as my scholl work is not a lot.
