Do you guys have múltiple choice questions? And math with numbers?
What is this equation? When I see 1/(2πi) I immediately think of inverse Fourier transforms but the DT (instead of dΩ) shoots that down, then I see strange nested logarithms.
Found the tests for the post office's horizon system.
For me that means 12 is a no.
lol I was struggling in AP statistics, but our midterm and final were all multiple choice so all I had to do was plug in each option to see which one was right. probably would have pulled a D+ out of that class if it weren't for the incompetent teacher
and I'm not just saying that. The only reason I got through that class at all is because I sat between the future valedictorian and the salutatorian and they were capable of teaching themselves out of the book, then passing it on to me. I was in this guy's class for an entire year and about 6 months in, he said something, and everybody's heads snapped up at once because it was the first thing he'd said all year that made sense.
Sometimes i wonder, am i the only one who found it much easier to reverse engineer the required formula from given data, multiple choice response and the different but similar formula on the other question?
Once had my class turn against me because a very unskilled teacher wrote a question on the test of which we hadent seen the required formulas in class. But that couldn’t be said the teacher because i the kid who was known to not be able to pay attention to annything found the correct answer.
And that kid's name? Everyone Clapped.
No, they hated me. Also because i was the only one to pass the exam, not because i was great but because the teacher was so bad that i ended up on top because not being able to pay attention in class was my default. So it didn’t make a difference how bad the teacher was for me.
Dont ask me to remember 3 different numbers at the same time. I literally cannot do it.
All the time, although nothing this complicated.
Find X in this formula... okay, I'll just put in the 4 choices and see which one works.
Find X where X is a modifier (a series of calculations) to be used with the provided numbers to end on a specific answers.
And i often had like 3 different sets of provided numbers and answers to verify if the series of calculations are goin in the right direction. Once you have sm that answers all 3 questions you known its gold.
Last step is restructuring the “modifier” so it actually looks like a formula.
And this is why my math teachers never gave multiple choice tests
As a kid who had a habit of reverse engineering shit, (malware analysis and ethical hacking my beloved) I genuinely don’t know you can reverse engineer an equation with a question and 4 answers, 3 of them which are wrong. Even with two questions, its still a crapshoot, and the amount of wrong to right answers seems a bit time consuming to use to try and figure out the real solution, much less the equation, in a reasonable amount of time needed to complete an exam.
It depends on the exam. One exam where it was totally possible was the EEE aero MAT for imperial college London. They have retired it since but i got about 50% (i know someone who got an interview with a negative score) because whenever the answer was a function, i could plug the function into the question ratger than do it from first principles (eg differential equations).
Maybe reverse engineering isn't the right term.
Brute forcing using the provided calculator and calculated guesswork till i got something that matched one of the answers.
I sometimes lost points for “something off in my formula” but the answer was correct so i passed overal.
I have a nack for “visualizing” certain math allowing for calculated guesses. I had a few instances (not on a test) where i literally just told the teacher i had not the faintest clue how to tackle the solution but it just screamed “x=3” and i was kindly told “well done, but no points without formula. “
I imagine what is going on is the answers on the multiple choice questions weren't random and you were picking up on the pattern then retroconing a justification. Say for example
- A. 12
- B. 14
- C. 11
- D. 68
You threw out D right away because it was much different and argued that it had to be A or C because being off by one is an easy mistake. Now it's just a question if even or odd, so you looked for a divide by 2. If found you went odd, if you found a multiple by 2 you went even.
Added to this you probably noticed a pattern. If C was the correct answer the next one was always A, etc.
If you aren't convinced that its just really good test taking ability it would be pretty easy to use an AI and make it quiz you.
Yeah I mean in some cases it's not hard to surmise. Given the context (class, diagram) and how many numbers you have assigned, what formulas are available to you, you might be able to guess the teacher shoved the numbers into the wrong formulas to create the incorrect answers. For some classes simply supplying nearby numbers to the correct response might not be "real" enough.
Student logic is certainly a thing, but I can't image it much help for the complexity shown in the meme. Basic geometry or math word problems as found in biology or statistics? Yeah sure
