Had friends who did the foundation chem unit because they didn't do chem in yr 12, and well, from looking at what they were doing, it was reall easy, (this is ENG1070) it was kinda a joke of a unit tbh...., the unit didn't seem to cover everything it was supposed to. I suppose thats what happens when you get a lot of people who dislike chem in the same room and try to make them do so chem. But then that could just be once off.
But yeh, in the single degree its an elective, and I don't think (not 100% sure) that its required in the double, but as JinXi said having a little bit of chem knowledge will help with parts of the MAE2400 materials unit, I knew what was happening with certain things in the lecture while my friends who didn't do chem had no clue why certain things happened, and kinda just applied it blindly.
