My dad borrowed a couple of my engineer books. He said they had more material and harder problems than his old college books did. Also my instructors said they fretted about trying to figure out what to teach out of the ever growing body of work. When my dad went everyone graduated in four years. When I went was more typical to graduate in 5 to 6 years. And they worried that they wouldn't have enough four year students to meet accreditation requirements. Same time I never heard my professor complain about the poor quality of students.
