I am changing to Farmer's Insurance for Auto Insurance. My agent tells me that they will need to scan my college degree for underwriting to process my application and discount.

My questions are the following:
1. What will underwriting do once they receive the scan?
2. Will they sell my name and info to marketing agencies?
3. What does college have anything to do with auto insurance?
4. Are they going to call my work and school to verify information (not that I am lying, but I like my private business private.)?

Thanks for your time.
