At my uni, Physics 100.

Every year, out of the class of ~300, 200 fail.
The re-sit exams are notorious for being more difficult than the original, as well.

Genetics - All biology majors have to take it, and complain it's hard.

Biochemistry - Not really a filter, it's just that most genetics students are too lazy to take an "optional" course that is essential for any advanced understanding of their field of study.

Everyone I knew damn near failed that class.

Most of my friends however were pre-vet and for them it was:

They would often do really poor in it, then have to either change majors or find another career path as they weren't getting into vet school after that.

I'm not sure where you're at, but my friends either struggled with it, or tried to place out b/c it was that hard.

You have to get in the box to lead them outside of it. I find that the notation of algebra is the sticking point for a fair amount of the students I've tutored, and by replacing the x with something that communicates the concept better (like a box where they write the answer), it's easier to make headway and bring them forward.

For the y=mx+b concept, the easy way to make it stick with them is to populate a graph. Have them populate the graph by plugging in different input x-values, and let them see the output pattern arise for themselves. Change b, and repeat the process. Change m, and repeat again. It's essentially the scientific method, and it shows them that they can do it without your guidance, which is really what matters, especially in math where a lot of students tend to lose confidence without really exploring their ability in the subject.

>>8924716
is this b8?
1.) I said I didn't mean it condescendingly.
2.) How can one get 130 on a IQ test(when they are not a child and are almost an adult, no less) and not understand algebra? 130s are engineering and comp sci lvl IQs and algebra is not. That just doesn't make sense. Even if they had a learning disability with a high IQ, that's always something associated with verbal or reading comprehension: their Input/Output is damaged but the internal processor is still good.

not that anon, but you would surprised at the amount of damage bad teachers can do in middle/high school. Only after many years I realized that studying for math requires tons and tons of practice, not simply rote memorization of formulas, which many high schools taught. Drawing the graphs and figures in problems helps with visualizing the issue, but again, this is never taught in high school, just "shut up and learn this because I told you to"

I agree. Math shouldn't be mandatory past 9th grade, most kids will never need to know parabolas and the volume of a sphere outside of math class.

Then, once teachers won't have to worry about having to dumb down their curriculum to make sure Johnny Brainlet passes 10th grade algebra, they can actually work to improve math education and teach math to students who are actually interested in the subject rather than taking it for a high school credit. It's fucking unbelievable that the average high school here in Canada doesn't introduce calculus until the very last semester of 12th grade, and it's a severely half-assed calculus to boot.

It's nice to know that I've taken all those and passed, even with my terrible work ethic. Real analysis was a bitch though. You really have no idea what pure math entails until you take a course that's purely proof writing. Pretty helpful for computer science and philosophy though. Or just reasoning ability in general.

The basic weed out courses at my university were the calculus series, foundations of programming, the intro physics series, intro chem series, and bio. These courses were all made to be pretty hard. They crushed a lot of dreams and stroked a lot of egos.

For pure math, real analysis crushed a lot of people. I heard topology at my university was suppose to be really hard but I never got to take it. I did do some of my girlfriends homework at some point for that class when she got stuck though, so it couldn't have been too bad.

>Post brainlet filters.

I used to teach introductory programming to CS majors, and I was explicitly told by the department head to make the class nice and hard, so it would serve as a brainlet filter.

The problem was that too many students were going into CS without a clue what it really is, so we needed to weed them out early so they wouldn't "clog up the pipes" (so to speak) in the later courses.

I think it had something to do with funding formulas. I think if we ended up with too many students waiting until year 2 or 3 to change their major out of CS (instead of year 1 like they're supposed to) then that tended to make students take longer than 4 years to graduate, so I think the department was penalized for that in the funding -- or something like that. (I was blissfully unaware of the gritty details.)

>>8929504
>>8926091

You use the "chaotic neutral" notation when you're taking higher derivatives (second, third, etc.) and you need to start generalize it as being "the nth derivative of f at x". In that case, you use a "(n)" superscript over the f.

You would only use a "(1)" superscript over the f if it was part of a larger example where you were looking at all the derivatives from the 1st to the nth, and you just wanted a consistent format for each one.

>>8929529
I asked about the chaotic evil notation. I'm familiar with everything else.

I just looked it up. It's Newton's notation. It's basically neutral good notation but dots instead of a line. That explains why I've never seen it.
