In general, which is harder: Mangerial Economics or Biochemistry?

<p>I'm switching out of Biochemistry to Managerial economics because I think it will be easier for me. My sister warned me : Managerial Economics is not easy ,and that many kids flunk out of it. </p>

<p>I dont believe one bit that managerial can be harder or even as hard as Biochemistry, which requires physical chemistry and O chem classes. </p>

<p>So in general, which of the two majors is harder? Which flunks more kids? Has lower average GPA? More study hours per week?</p>
