The interviewers want to know whether you'd have the support required for this challenging chapter of your life and are looking for assurances that you'd be able to sustain your commitment through graduation. There is also the aspect of financial support and navigating your way into the real world away from home, especially for those who attended community colleges before branching out. Therefore, the support one's family and friends offer can be instrumental in your chances of success. Discuss your support system and the manners in which your family and friends support your chosen career path. If someone in your family has dentistry experience, don't leave that on the table.
