hi Krystal.you could start the sentence by saying i feel i can contribute to the school as i am good at??? i had good grades at my last school in ??? too and if you have a sport you are good at you could mention that too…. i work hard i am not disruptive in the classroom ….i try to help other pupils if they have difficulty in understanding??? …… Heads are usually proud of their schools and its achievements so if you have an outdoor sport like netball..running or something you really excel at and you get them a mention in the local paper you will be well thought of .so think ahead a bit hunni sometimes if your written work isnt 100% you can get away with it if you are good at a sport lol been there !! i was in the southampton netball team i got picked from school so my head forgave me the fact i wasnt too acedemic . good luck in the new school hunni i hope it all goes well for you and some of the suggestions help you out with your application xx

I would contribute to the school by joining (and here you mention either clubs or sports you would join) and by attending school activities.

I would be an asset to the school because I have excellent grades and would lead others by my example.
