You can't apply any discount, on your own. It must be initiated by the company. after you inquire and provide proof, through your agent. Therefore, if you speak with an agent, instead of only working through a website, you might qualify for discounts. The website will not give discounts. To qualify for the good student discount, you need to provide a notarized transcript of your grades, and it only applies to high school, not college. Attending driving school also only applies to a minor, not an adult. Therefore, neither discount applies when you get your license as an adult, in most cases.
Remedial driving classes may get a discount (from high risk policy), if you have had an excessive number of tickets, and would otherwise lose your license for 6-12 months.
Speak with your agent about your situation, and explore any discounts that might be available, especially if you take out renter's insurance, or other liability policies with the same company.
