How many Dual Enrollment courses should I register for and what courses for my first year

This is my first year of doing dual enrollment this fall. I’m a rising senior and I wanted to know how many courses should I take if i’m doing dual enrollment part time and what classes should I take since this is my first year? Im trying to major in business when I graduate High School. I also want to know what days I should choose to do my college classes and what is credit range?
