I have heard (though don’t quite believe) that they can collect data on emails; so open all emails from them, maybe forward the interesting ones to your parents.
If you have any questions that cannot be answered by looking at the website or elsewhere on the internet, contact your regional rep by email. Be respectful and engaging. But don’t email if it’s an easy question that would be a waste of their time.
Request an on-campus or alumni interview. Send a thank you note after.
