In this context, "aced" means that a student got the letter grade "A" in a class, or multiple classes. For example, this sentence means she got all "As" in her probability and statistics classes. Ex: I aced all of my classes this semester, so I am proud of myself. Ex: She aced all of her science classes, that's why she's so good at science.
