I'd say this is the most common. And it's not prepared as in knowledge wise, there's just not any handholding anymore, and a lot of students lose track. It's smooth(er) sailing after the student realizes he is improving himself, not being improved upon.

There are always outliers in terms of classes ability to grasp concepts and pass examinations. However if this 50% fail rate is with a sample size of thousands, then there is something inherently flawed about this class. If this class is too "advanced", and this is the reason, then they need to have more prerequisites to enter. If the fail rate is not due to a lack of people who intellectually able to pass, then there is either an excessive amount of work that is required for the class that is unreasonable. Lastly, if the professor is horrible at conveying these concepts to his students or is grading unreasonably, the professor must be changed.

Ultimately if over a large scale the average is not a bell curve around a passing average that is consistent with a sufficient understanding what is taught, one of these problems is occuring and must be fixed.

University may not realize it but they need to get off their high horses sometimes and recognize issues. I mean, its also for profit so they probably make money from people retaking a class. However, my points are to be considered in a vacuum.

they just don’t care, there’s no reason to care if you already have the checks from the gov or their parents. You can always just enroll more hungry freshman if the current class is thinned too much.

Are you retarded or a CS major? I haven't used a calculator in any of my calculus classes because you don't need one- it just be almost stupidly easy. You could reasonably self teach yourself Calculus 1 in maybe 2 or 3 weeks of continuous study. If you couldn't do that then I hope your degree doesn't require any mathematics past Pre-Cal and you just took this class for an elective.

>I haven't used a calculator in any of my calculus classes because you don't need one
But you will, later. So practice using one now on the easy stuff. Calculators are tools and this Luddite mentality is cancer.I could wipe out the 40 questions in 10-15 minutes with my TI-84 just automating stuff like the quadratic equation. I DON'T NEED TO WRITE OUT THE QUADRATIC EQUATION 40 TIMES.

>You could reasonably self teach yourself Calculus 1 in maybe 2 or 3 weeks of continuous study.
No shit, but I have to take a math class, AND I'M PAYING TO TAKE IT. So I expect to actually learn calculus and not remedial algebra.

>If you couldn't do that then I hope your degree doesn't require any mathematics past Pre-Cal
It doesn't I just always liked physics and enjoyed the pre calculus we did in high school. I could have taken the piss easy watered down calculus class they offer but if I have to spend months in a classroom I want to get something out of it.

Is that a lot or not? In my uni exams were worth about 70% of our overall grade and there was one exam for each course and they were all within one-two weeks of each other in spring.

The rest of the overall mark was usually labs and projects and smaller units which mostly weren't tied to any specific course directly so essentially the grade for each individual course was 100% exam.
