Test

Post Reply New Topic

Took a test yesterday and trying to convince myself that my answer is right but it is in fact wrong so far. I wrote down different isomers that was needed for octane. I wrote isomers with isobutyl, isopropyl, isopentyl. I'm trying to prove that even though I am wrong, that since I was able to pull those out of my ass to answer the question and hardly studying that I should get some credit for the answers.

NO.

Damn, then I probably failced that test. Gpa is not looking good this semester.

If you don't study and learn the material you shouldn't be rewarded as though you had. Guessing one's way through a test should not be tolerated as it devalues the reward of success for those who actually have bothered to learn what they were supposed to learn.

Sorry. We were never taught correctly in the first place so how am i suppose to answer correctly? See why I said what I said? My teacher is a poor teacher and thus education is not being given the way it should be. A teacher is suppose to TEACH. We have not been that. Clearly. My teachers are not masters and doctors of the study. They usually have read the book once and try to teach it. So why expect the same out of us. We are being graded wrong. We shouldn't even be taught the material.

This all adds up to being taught wrong. So why should we be tested as if we were taught right and graded as if we were being taught right.

Everyone teaches themselves anyway, not the teachers. A teacher can facilitate or inhibit learning, but they cannot do the learning for you. It sounds like your school is using TA's as profs., and that is dumb, but still one must learn on their own whether in a formal or an informal system of education. Being graded well because you're able to guess at the answers and pull up slightly associated terminology to cyclooctane but only in that it's from a naming system for hydrocarbons. If you don't know the material, you shouldn't be able to pass. No student should. I know that colleges have required this and required that so that they can make financial predictions based on what major you sign up for, which is dumb and in some cases even able to be considered wrong, but even so if you take a class it should not be able to be passed until the knowledge within it is known and understood. This is why, in my opinion, many college students are idiots: the college system itself discourages learning from occurring, and instead encourages rushed busywork and multiple choice quizzes able to be passed by mere ignorant guesswork. It's not right and it should be changed.

I totally agree with all of that. To admit I'm one of those students is another thing. I am 50/50. I feel that I am capable of more then what I do. One hit to the head, let a lone 6 can do damage from what I have read.I fell off a chair at 4 years old and hit my forehead. Also at 5 years falling off a slide, 5 years old riding a bike, 14ish riding my bike, 17ish years old( 5 staples on that one) bike, and 18 years old bike(minor concussion). I Had a girlfriend for 1.5 years while going to school and am still recovering from that break up. Also echolalia of my ex. So for now I blame it on that for why I am not as good as the other students.

Also students are pre-meds, pharmacist, taking or have taken more math,physics classes/analytical skills then I am or have or have more learning experience then I do or are just innately smarter than me. I'm sure there is more to me then me hitting my head. My study habits aren't the best, and I missed 3 years of high school. The class is also at 9:30 in the morning. My life hasn't been the greatest to say the least. And yes, it was dumb of me to say that but I'm rationalizing my fantasy instead of taking the reality of it. I am strongly motivated to gain who I want to be. and plus I don't even want to know what is wrong with me physiologically. But education undermining and my huge paranoia doesn't help either. Also I shutdown in lab and during class.

If the answers were correct, then it does not matter if you derived them, knew then ahead of time, or guessed them.

But if the answers are flat-out wrong then you should get no credit at all for them, no matter where they came from.

Besides, guesswork is ineffective. If you have 100 True/False questions on a test, then you are likely to get only half of them* correct, and last I knew, a 50% score was failing.







(*Yes, I know ... the odds are actually 50:50 for each question, but I'm trying to make a point here with out taxing too much the comprehension of the OP.)

Thanks dick, I'm glad you can gauge my comprehension based on those 3 paragraphs. and four questions is 25% of getting right and 10 questions is 10%. New insult: 30% of 10 and 30% of that product is .9. wtf? smoothe. Or is that too incomprehensible for you?

Definition of a isomer: Same molecular formula but different molecular structure. So yes in fact I was correct. 2-isopropylpentane c8h18 is the same as octane c8h18. 2-isobutylbutane c8h18, octane c8h18. Same molecular formula but different molecular structure.

It's been too long since when I studied organic chemistry to mentally verify that, however in your original post you said that you guessed and that you hardly even study, and as such you should not have credit for it.

It was more of a educated guess. I dont really know what guessing means. I could slightly remember from the book then tossed what I slightly remembered from the book on to the paper.

That's better than your OP sounded, but what if you had just pulled up other terminology from memory and said "1,3,5, cyclohexane" instead?

I think that should still be right because the definition says(don't know about this) they have same molecular formula but different structure, it doesn't say it can't be a cyclohexane and it can't have unbranched alkanes/ isobutyl, isopropyl, isopentyl.

I looked and yes my choices of isomers are not isomers, but they do have the same chemical formula. So I don't see how they are wrong by that exact definition.

Are you saying there are holes in organic chemistry that need to be fixed or just that there are holes?

What? Neither. It's been over three years since I've studied organic chemistry, during which I've studied the mind numbing field of tediousness called accounting and all the gen-ed garbage that my former college could throw at me, so there are certainly gaps in my memory from when I studied chemistry last, but I'm saying nothing about the field itself.

K I'm not sure what you were saying then.
