What does /sci/ think of timed tests? I think they are bullshit.
My chemistry professor gives us a timeframe on our exams so we have about one minute per problem. Now, I understand everything conceptually, but math is not my strong point, so I need time to set up full dimensional analysis or work through calculations in a formula a step at a time, and doing this I get most of the practice and homework problems right, but I only get low B's and C's on exams cause with the time limit not only is feeling rushed working against me, but he expects us to know immediately what to do, including shortcuts.
Are timed tests just a way to create a more pronounced bell curve (separate the xceptional from even those who just good?) Any tips for dealing with exams like this? Are profs like this just shit?
I think the best is a combination of timed tests and take-homes, and they should both be realistic. As in, the timed tests should not have fucking arithmetic "gotchas" and the take-homes should be quite difficult and have somewhat open-ended solutions
I currently in your typical intro linear algebra type class and we also take tests that give us about a minute per question. This is quite annoying when we have to do something like solve large linear systems. It is a pretty easy thing to do but can take a bit of time.
OP here, thats the thing, they are loaded with arithmetic "gotchas." You'll have to deal with like g/ml, mMol, and the answer in lbs in the same problem, so fucktons of it are wonky conversions.
Sorry but it has a purpose. You have to spend your time thinking, not soing calculations. The point is that you have to do math fast and correctly on the first try so that you don't waste time on it.
But why does that matter? I'm a ChemE major. Boss says "durr hurr what is blah blah" I don't need to solve blah blah in 30 seconds right there, I can go back to my office, work through it for a few minutes, and email it to him after taking my time and verifying.
But you need to study before. And you only have limited time to do it. And you can't afford to spend that time computing triple integrals for one hour.
I have friends who literally can't do a fucking fourier transform in less than 30 minutes. What does that say about a potential scientist or engineer?
It also forces you to have a methodology. I tutor freshmen and it's kind of funny to see them struggle in physics because they fail to define a system or to choose adequate coordinates.
Once they acquired the methodology, everything started going smoothly and swiftly, and they could spend more time on the "physics"part, rather than the "algebra trial and error" part.
it's all about doing 4 quadrillion problems and seeing patterns/tricks right off the bat
which is funny because really quickly all that shit just becomes stuff you tell your computer to do and linear algebra becomes much more abstract and module theoretic.
are you faggots not allowed to have a TI-84/89? if you are, you have zero excuse for falling for arithmetic/algebra mistakes.
i've written dozens of little solvers for my 89 CAS. any material i see thats plug n chuggy, goes right into an algorithm.
>I'd rather just memorize the algorithms than learn BASIC
you still have to handjam everything in tho. what you are doing, is cutting out a huge amount of calculation time, and eliminating possible "fat finger" errors.
