To begin making an account of Common App, it requires me to list which I am and by the time I graduate high school I will have fully completed my degree as well. I know generally applying for colleges I am considered a first year student rather than a transfer student. Would the case be the same for this?
For most colleges, applicants who took college courses only while in high school but not after graduating or otherwise leaving high school are considered frosh applicants, but check the rules for each specific college you may want to apply to.
If you have taken college courses after graduating or otherwise leaving high school, that can cause you to be seen as a transfer applicant by many colleges, although some colleges may allow frosh applicants to have a limited amount of college course work after graduating or otherwise leaving high school.
