I’m in the exact same place with my D20 - although in her case the school only recommends doesn’t require. She’s waiting for her schedule to solidify for fall, and it’s highly likely she’s going to not take the second one (she already has Math 2). Even if she signs up for it, I question if she’ll have the bandwidth to do any prep which will probably just make it a waste of time and money anyway. It helps that the school isn’t her top choice, it may have made her decision more difficult.
