Retaking a low-grade class that I passed the AP exam on for UCs? + other low grade concerns

Thanks for your response. The two semesters I received in A in are both the only art courses my school offers so they are the same but at different levels (A in art1 one semester, A in art 2 second semester). Does this work out? Also, I plan to retake a class starting tomorrow online and plan to finish it by the app deadline. My counselor said it would fall under 11th-grade coursework on my transcript. Would they be considered, then? Also, how do I know if my DE course is UC-transferable?
