How many hours for principle EC ?? Please Help

<p>My principle EC is music:
Flute: Regional Orchestra, Windband, Senior Orchestra, Flute Trio etc and I estimated I spend about 16 hours a week on this. I thought this was enough but looking through other posts people are spending like 30 hours a week. Im really worrying now cos iv already sent in my app to stanford. Im international so i dont know approx how long americans spend on EC's ?</p>

<p>just one phrase - quality over quantity</p>

<p>The other posters, assuming they're truthful, may have included all their lessons & practice time (as well as rehearsals) in their hours. Admissions counselors know how much time it takes to achieve a proficient level in music. Don't worry about it.</p>
