Most high school students are planning to go to college, but some might not be planning to further their education after high school, it depends on the person. I think your best bet is to put a bachelor's degree because that is what most students aim for. For the second question, I think none because most high-school students don't have money to pay for that unless they have a job. It really depends, seniors might have more money then freshmen but the best bet would be none in my opinion
