Claim: Grading on a curve discourages students to help each other learn material, and is not conducive with the egalitarian perception of college as a place whose primary goal is to educate all its patrons to the best of its abilities.

Premise 1: College ought to be, or is at least generally considered, a place and practice put in place and funded in order to educate as widely and thoroughly as possible.

Premise 2: Many college classes grade their students on a 'curve,' or relative scale to more easily determine students more proficient at the curriculum. The more students you outperform, and the more you outperform them by, the higher your grade in the class.*

Premise 3: Placing highly on these curves offers advantages for students' in their educational or personal careers.

Premise 4: A student who successfully helps their fellow classmates understand the material in a curved grading scheme is lowering their own score.

Conclusion: Students looking to perform well in courses with a curved grading scheme are generally incentivized not to help their classmates, barring paid tutoring or other deals.

*Note: There are other problems with curved grading schemes, such as the majority of the class performing very well or very poorly on a normal scale, but the best of those students will still get good marks despite being under or over challenged, which essentially boils down to lazy curriculum construction.

Spaced repetition is my primary method for developing new insights and "leveling up" my mental scaffolding of any discipline. The times between seeing a new card, I often find my subconscious has worked through some implication I wasn't previously consciously aware of and when I see the card, the buried thread of understanding reveals itself. If you think SRS is just "memorization", you are a fool. Note that Von Neumann was renowned for his prodigious ability to memorize and he made it a point to be able to recall a vast corpus of mathematical formula.

This was 3 years ago, on my final bachelor's year. There was nothing to gain and I actually hold no grudge against the prof. He's just an old grumpy guy. Sure, what he did to me wasn't right, but I can understand his point of view ("this lazy fuck is the only one who hasn't done the homework and then makes up some method I can't understand and the solution doesn't exactly match") even if I don't share it. Repeating the exam was way less effort and trouble than reporting him or requesting a third person to review the exam.

>>10449455
>>10449589

You can prove your qualifications with certifications, online courses, and projects. However, not every company is going to be willing to hire someone who has no degree. And some countries (like my home country) demand a degree to be able to sign engineering projects. You obviously don't need a degree to release some code, but you sure do to sign the plans for a building, structure/utility calculations, etc.

>> No.10449656

all grades are graded on a curve. the standard approach of 70-C/80-B/90-A is a grading curve. furthermore, the convention that 70 is a C is just that, a convention. if the course material is designed so that minimal mastery of the material gets you about 50% of the questions right and a C, that's not a bad thing, that's grading working properly.

plus, it's actually better to put the minimal mastery grade closer to 50%, because it gives you more power to discriminate at the upper end of the scale. nobody gives a shit whether you got a 20% or a 40%, you still failed, so why do we devote a whole 60% of the grading scale to failure? we're squashing all our descriptive power for true accomplishment into the top 30-40% of the scale.

>> No.10449696

>>10449656

The American grading system is retarded. Exams are easier and grades are inflated. 70% is your European 5/10 or lower, so the dynamic range to discern good students from great students gets shortened.

In my home university, you could spot a bad student because he had to repeat 5-10 courses 2-5 times because students can actually fail exams. If you fail a final, you can repeat it once, and if you fail again then you have to repeat the course. The best grade in a course might not even be an 8, because 10 means actual perfection. When you finish your degree you get a bonus to your average depending on how many times did you have to repeat a final or a course. After the boost, if you have more than an 8 you're probably in the 90th percentile for STEM degrees, and there's going to be 1-2% of people who get a 10.

You seem to think that every university program is CS. It's not. There are no github portfolios for engineering degrees. No one is going to hire a civil engineer without a degree. Where I live, you need a P.Eng to practice on your own and to get that, you need to work under an engineer for a certain period of time. No engineering firm is ever going to hire you without a degree. If you get a diploma as a technologist, you still won't ever have a path to becoming an engineer without going to school because no one is going to trust you with tasks you're not qualified to perform. In the business world, this is a liability that isn't worth taking for any employer, no matter how smart you think you are.

It's also extremely arrogant to think you can learn everything on your own. Self-taught wunderkind geniuses are extremely rare. Do you think Newton didn't go to university? Do you think Ramanujan learned absolutely everything on his own? Every man is not an island and people who subscribe to this mindset often take many of the opportunities they have had for granted. Granted, there are lots of shitty instructors at universities and some courses might not be perfect - they might be downright bad - but by attending those courses, you still come out better than if you go it alone because you get the benefit of getting feedback that you won't get from some coursera shit.

Frankly, if you aren't responsible enough to pay down student debt, you probably aren't responsible enough to build bridges anyway.

Valid argument but there should be other ways than paying a gorillion dollars for university to get the necessary qualifications.
>It's also extremely arrogant to think you can learn everything on your own.
Most people practically learn on their own at university anyway, attending a lecture is no different than reading a book/watching a recorded lecture. And if you get stuck on something, you aren't on your own in the age of the Internet.
>you get the benefit of getting feedback that you won't get from some coursera shit
You're comparing the average self-learner to the good university students. I doubt that someone making a genuine effort to learn something on their own wouldn't end up with more knowledge than the brainlets who are just in it for the degree and pass with shit grades, despite the lack of quantifiable feedback.

University courses are designed for the average student. If you're smarter than the average university student and you are self-disciplined sure, you'll learn more on your own than at uni, because uni pace is too slow for you. If you're average, though, I don't think there are any benefits.
