AP Stats or AP Calc BC

<p>I have a dilemma deciding which math class to take senior year. I'm currently a junior and I'm in AP Calc AB right now. I received an A in the class first semester however I barely have a B this semester. I don't know whether I should to take AP Stats next year or AP Calc BC. I feel like I am good at Calc however my borderline grade this semester is scaring me. I want to major in chemical engineering in college so which math class would be most beneficial? I also have a pretty rigorous course load next year and I want to have a couple of easier classes since it's my senior year. What should I do? Thanks!</p>
