<p>I'm sorry if this is common knowledge, but I am the first person in my family to apply to an American university and I couldn't find the information online. </p>
<p>For first time applicants to Columbia University, where should I tell my teachers to route my letters of recommendation to? Is it Naviance, CommonApp, or something else?</p>
<p>Acquire your teachers’ email addresses and send them an invite through common app. Some schools use Naviance (I used commonapp) so talk to your Guidance counselor.</p>
<p>I got lucky and managed to secure personal guidance from my counselor 
Thanks for the confirmation, though!</p>
<p>However, I was wondering if Columbia will accept additional letters of recommendation beyond the 2 required from core teachers. Is that alright, or will I bother the admissions officers by giving them extra material?</p>
<p>Some schools specifically state try don’t want extra recommendation letters while others accept them if those letters provide new information and a different view of yourself so check Columbias website to see their position or ask your guidance counselor. You can also try emailing or calling their admissions office.</p>
