<p>I heard counselors can submit a electronic copy of your high school transcript via the Common Application. Should I still mail a official copy to the schools I'm applying to using the Common App? </p>
<p>No. Whether via mail or the common app, the transcript needs to be sent by your school.</p>
<p>I think OP meant should his/her high school send his/her transcript through mail. But the answer is no, the colleges only need to receive it one way, and you can check on the Common App if they’ve received it/if they’ve downloaded it.</p>
<p>@enigmaticescape thank you for your help. </p>
