<p>I'm taking Econ 2, and I have an A in the class, i know all the concepts and can apply them without any trouble.</p>
<p>We had an exam today, and on the final 5 questions I had to use a graph to find 5 answers.</p>
<p>The first one was find to marginal cost - Easy, wrote it down without a problem.
The second question asked me to find total fixed costs- I knew that all it was was the total cost when input/output = 0. It was 5.</p>
<p>Somehow I must have blinked out and instead of writing the answer I knew, I wrote some stupid random number (I think i put down 1, and I don't know why!). I was a little sick and tired during the test but still!
So, using the wrong number I found the wrong Average fixed and average variable costs!</p>
<p>This series of questions(5)was worth 25% of the exam. The moment I handed it in my mind just went "*** MAN!", but it was too late.. I know i missed 3 out of the 5 on that part alone, and I have no idea what else I'll get marked off.</p>
<p>Basically, now I went from a 90+% grade (which is an A) to an 80+%(a-, if that)</p>
<p>I was told by the professor that if he sees a trend toward good grades on exams, and i mess up one, its probably no big deal, but I cant help but be furious at myself.</p>
<p>Has anyone else had this?</p>
<p>Edits - I am not in a good state of mind right now and I cant even put sentences together...</p>
<p>I woudn't worry about this, hopefully your professor will see that you just messed up a number, but knew that you knew how to find the vc and fc. Regardless, one grade isn't going to kill you.</p>
<p>This kinda stuff happens occasionally. one thing that i have learned, through my very minimal college experience, is that you always have to check over your exam for these kinda stupid errors IF you have time left over. ive made really stupid mistakes on my midterms like inverting the wrong numbers and forgetting to balance the chemical equations.</p>
<p>Worst mistake(s) I probably made was on a chem test, where I had everything set up right on paper, but accidentally added a digit when punching them into the calculator. It was a series of questions where the answers to the later questions relied on the answer to the first one... I lost quite a few points because of that. Fortunately I got the bonus question he gave us correct so I was still able to get an A. But I'm a perfectionist, so I can't help but get mad at myself for losing so many points to stupid mistakes.</p>
<p>moral: bruinboy's right, double (or even triple) check your answers if you have time.</p>
<p>Is it possible that your professor will grade it where if you do one part of the problem wrong, he'll only take off for the one part of the problem that affected the rest of the 3 questions? I know I had a math teacher that would do that...if we calculated one part of the problem wrong, and we used that answer to calculate other problems (obviously giving us the wrong answer on those, too), he'd only take off for the initial problem if we did the work right in the other problems...</p>
<p>I hate that feeling whenever your gut instinct tells you to go for one answer but in the end you change it, most of the time when I do this I'm always wrong. I literally slap myself when this seems to be the case. I took a test in Pol. Science on friday, had I not gone over my test I would have missed 3/60.</p>
<p>I completely blanked on my first Chemistry test...about significant figures...which was a huge part of it...I wanted to shoot myself in the face. So yeah, I made a 68 on it and totally screwed myself out of an A in the easiest class ever (ended up with a B). </p>
<p>But it wasn't the end of the world, so don't worry about it. Everyone has their moments of, "Why the hell am I so stupid?!" </p>
<p>Besides, if you only missed 3 questions on that part and maybe one or two on another part, you'd still have a B or a high C. Just make sure to get enough sleep and all that good stuff before the next test(s) and you should still be fine with the A thing.</p>
<p>We've all done stuff like that. I'm now very careful to check my tests because I usually skip questions I'm not sure of and go back to them later, but there have been times when I forgot to go back and ending up leaving them blank, and realizing it 5 minutes after I leave them exam. Whoops! It happens, and you'll do better next time.</p>
