I work with a couple of university exectronics departments and they all say the same things:-
Standards of under graduate students has dropped substancialy over the last ten years due largly to the fashionable idea that failing exams is a bad thing and leads to people being discriminated against,so basically if you can spell your own name correctly on the exam papar you pass the exam and you can go to university.
Very few students are going into engineering subjects so funding is cut by the universities in favor of more profitable subjects such as business studies.
There are very few suitable graduate students who can be used to teach undergraduate courses,it used to be that graduate students were required to teach at undergraduate level,but as there are now so few engineering graduates numbers have to be made up with mathematics and physics graduates.
students who do enter engineering courses get discouraged and drop out at an early stage after having taken the places of other people who might have been more commited.
The answer is to write on the top of all exam papers'There are some people who will fail this exam,this is because they are not very bright,get over it'
