<p>hey i'm an australian, so high school is from yr. 7-12. Am i expected to send every report? Will getting Cs (though this was in compulsory sport classes) in year 9 affect my application if i'm planning on applying to ivy league schools.</p>
<p>there is no solid answer to your question regarding your grades affecting your admission chances. You first need to post your stats.
Even if high school means 7-12 in Australia, in the US high school means 9-12. That means you need to send results of your academics between 9th to 12th grade</p>
