Dual Credit From HS affect college GPA?

Does your grade from a hs dual credit affect your college gpa, specifally Purdue? If I am taking multiple difficult class (AP and dual), will my gpa matter much if its slightly lower because of the course? Its not like im getting B’s all the time but occasionally 1 or 2 per year.

Your GPA is defined by your HS. Colleges will look at your APs and dual enrollment and see the academic rigor you have which is a separate part of the evaluation.
