Rate my EC's for Top tier/ Ivy league colleges? Will rate/ chance back

<p>I understand that spreading yourself out thin and not really focusing too much time in a few specific extracurriculars is bad, therefore since 9th grade I've tried to tailor my EC's towards science/computer science( I want to major in it), and taken advantage of the opportunities I've been given. Please rate my EC's in regards to application to any top tier college(Cornell, Princeton, Hopkins, etc.)</p>

<p>I am a junior. </p>

<p>These are in order of importance(in my mind). Activities 1-2 may alternate in importance, 2 may become significantly more important to me.</p>

<p>what year are you in?</p>

<p>Junior!</p>

<p>You should be fine for most top colleges in terms of ECs, but remember that grades matter just as much.</p>

<p>Honestly, your EC’s aren’t particular tailored towards stem, there’s no aime, science fair, stuff like that. Paid courses at a university are good, but they don’t carry much weight. However, you have shown commitment to your existing EC’s which is always a buff.</p>
