In ANDS! defense, I interpret it similarly, based on the provided articulation.
Nevertheless, ug classes can be absurd at times (as can grad courses). If you find it to be a waste of time then I would pursue the other course and work hard. I assume by your concern regarding your standing that you aren't performing well. (ANDS! probably also linked this to the urgency of the question in relation to avoiding an upcoming assignment.) If this is, in fact, a concern then you will need to decide whether you can manage the heavy course load.
