I’m leaning towards having them list his math class on there instead since he is unlikely to use it for engineering. That would solve an immediate concern. We do know that this science class will transfer to one of his target schools as fulfilling the entire year of science required for engineering majors.
As an aside, our state has pushed high schools to allow students to earn college credits more easily by graduation. Since our school doesn’t do AP or IB (though plenty of kids take the AP tests), the HS seems to be offering more dual enrollment classes. I’m a bit ‘meh’ on those because I’m not convinced that those credits will transfer at all. I don’t mind my kids taking them but I don’t like the mish mash of transcripts that arise. My senior will have three college transcripts to send off with applications and my junior will have at least that many - possibly four.
Really it may all go out the window if either goes off to a private college.
