Chem, Phy I & II, and Calc I & II were the "weed outs" when I was in school, and it was no different for DD. She did fine through all that, but 40% of those taking the Physics classes got a D/F. She also encountered a Dynamics prof this past semester who appeared to be on a mission. She survived that as well, but ya gotta love those tests that look nothing like the homework or in-class examples. He created his own exam problems...ones that made other profs shake their heads.We didn't have a weed out class that I can remember for Engineering. If Physics II was Electricity and Magnetism I didn't like that class either..lol.
