"Because you are applying to business schools, you really should look through this and make the most professional appearance that you can," Skarlis told Rachel.
He took a look all the way back to when Rachel was in middle school and first started using social media.
"A lot of people don't understand it's archived and it's available," Skarlis said. "You might never look back there. But an admissions person might do that."
He also suggested students search themselves on Google, something a college admissions person is also likely to do.
"It may not do the trick to have privacy settings because the Internet is huge and vast and ever-expanding, and sometimes if you Google a person you can find out a lot more from one of those social media sites that sneaks through those filters," Skarlis said.
After deleting a video and reviewing a few pictures, Rachel's Facebook profile presents a much better picture to the colleges she's applied to.
Here's a list of seven easy steps to help you clean up your online profile:
1. Keep a clean account free of inappropriate postings and pictures from the minute you set up your account.
2. Know what your friends are posting, as well, and make sure they aren't posting inappropriate pictures or videos of you.
3. Tighten privacy settings so that only your friends can see posts.
4. Google yourself so you know what is out there. Even though you set your privacy settings on social media, search engines can work around those filters.
5. Remember to go through old postings, too. College admissions people often look all the way back to when you first joined social media.
6. Check your social media pages about once a week.
7. Rule of thumb: If you don't want your parents to see it, take it off.
