How to build up credit?

peaches

Hey ladies! So I’m 18 years old and I want/am going to move out with my boyfriend within a couple months. Honestly I have no education on credit or credit cards or scores or anything! All I know is that my parents are in debt and I definitely don’t want to follow in their footsteps. I actually checked my credit score the other day and it was a 650 (I didn’t even know I had one because I don’t have a credit card). I do have a store card for VS but whenever I use it I pay it off within a week. Do any of you have easy tips to get your credit score up? Also, any advice about all of that would be greatly appreciated! I wish high school taught kids more about this!
