<p>Sorry, I have been asking lots of dumb questions </p>
<p>but just one more if you don't mind..</p>
<p>Just a moment ago, I complained to my mother about how much I lack ECs,
but my mother has just remined me lots of things I did in China before I immigrated to Canada...</p>
<p>1)I got the violin grade 10 certification( which is the highest grade for amateurs in China)</p>
<p>2)I won the 2nd place in a violin competition in China</p>
<p>3) I once was a member of a string quartet band</p>
<p>4) I participated in a violin performance with a extremely famous violinist named Lu, Si-Qing in 2002.</p>
<p>I just want to know if the activities listed above count for ECs, and does Stanford require the proof for these things? </p>
<p>Well yes they only look at your grades after the 9th grade. However, the Stanford application also asks that you list the activities you have participated in since the end of 9th grade. If you are still doing these activities then you can most certainly put them on your application. If you would like to explain your prolonged involvement in an activity, you can do so in an essay. However, if you have not participated in these activities since the 9th grade, you will be unable to report them to Stanford.</p>
