My four that went to ISU just had AP Calc AB, I think, so they all started with Calc II. The curve sometimes got thrown by students who had already taken AP Calc BC and were taking it at ISU thinking it would be an easy grade and they could then count it in GPA. It worked out for some but oldest ISU son wound up tutoring one of those guys who had already taken some of the Calc II content.I wish he would've tried to apply to some of the prestigious institutions to see if he would've been accepted. But he had his heart set on ISU from the start. He toyed around with ASU, but when his nerd herd buddies all decided on ISU he was set. His first calculus at ISU this semester is Calc II and that has been a wakeup call. He's doing fine, but it's kicking his butt.
Those Calc series can all depend on the prof you get, some suck and then you take departmental tests that your prof may not have covered the material well. Was better for my younger sons as the older ones told them who to take and who to avoid.
My oldest who went to ISU actually got a better scholarship deal from Notre Dame but at that time they did not have the specific engineering major he wanted. They added it two years later. The other three all got a better scholarship deal from ISU than ND.
My only son who didn’t go to ISU wound up with Cyclones as his runner up, as at that time ISU still had the full ride for National Merit scholars. He picked a lot of the schools he applied to based on who gave those scholarships. Ultimately he just could not turn down Caltech. He and many of his Caltech friends were turned down by MIT and the thought was that MIT is harder to get into for white and Asian males since they do try to admit a diverse class. I was surprised he liked Harvard when we visited and he applied and was interviewed for that one. They had tons of applicants because that year was when they started with the full ride for families under $100,000. He was wait listed there but I think he still would not have turned down the Caltech offer if he eventually got into Harvard. Getting the big packet from Caltech in the mail, he had tears in his eyes before he even opened it.
