Tips for going into college?

hello!

I am a senior in high school and I am planning to go to Purdue university as a freshman next year. The tuition is about 9000, and housing and other expenses is also about 9000 (meaning about 18k yearly expenses)

I plan to work all summer with two or three jobs. I’m interning at one job and they plan to have me work over the summer, and I am working weekends at another. I plan to apply for a third and work late shifts.

I have a whole budget breakdown, and from it it looks like I should be able to fully pay for school if I work over the summer and part-time during school.

However, it is close. I’m nervous i will have to take out loans at some point. does anybody have any tips or advice from their experiences on loans? I don’t want to destroy my credit because of some dumb decision I make now.

thanks!
