What is a passing score? I am currently making a 97.54 in my English course and I all I have left to take is the exam. I was wondering if someone could help me figure out the lowest score I could make on my exam while still making an overall score of at least a 90. (This is just in curiosity) The reason I've come to open study is because I don't understand the grading chart, but I do remember someone from here once telling me the right answer - so I figured I'd ask again.

does it say how much weight this exam has?

jimthompson5910 (jim_thompson5910):

ex: this exam is 10% of your grade

OpenStudy (anonymous):

It doesn't, and that is one of the parts that had me confused because all I have to go by is the little chart.

jimthompson5910 (jim_thompson5910):

and that's the only chart of info it gives?

OpenStudy (anonymous):

yeah, when I click on my grade book, that's all it shows I can see. I was looking around to see if I could find something that would give me and idea, but that is all I have.

jimthompson5910 (jim_thompson5910):

alright let me think

OpenStudy (anonymous):

It depends on how much the test is worth, and clearly many other factors, the teacher could decide to curve the test, to weight it differently, to do a variety of different things.

jimthompson5910 (jim_thompson5910):

let's consider a very extreme scenario if the final exam is 90% of your grade, then 0.9754*(1 - 0.9) + 0.9x = 0.9 and solving for x gives you x = 0.8916222222 which means you need to get at least an 89.16% on the final if the final is worth 90% of your grade

jimthompson5910 (jim_thompson5910):

I'm sure the final is definitely not as high as 90% of your grade, but you get an idea of which score to get (at least) and you know you'll be safe and be over 90% overall

I like that example! Thank you. I will definitely keep that in mind.

jimthompson5910 (jim_thompson5910):

you're welcome your best bet of course is to ask the teacher (because s/he may grade on a curve)

OpenStudy (anonymous):

I understand. I am in the middle of my exam (online course) and I saw a few questions I was unsure of so it made me curious, but hopefully if I do even make a lower grade I should be safe. Thanks for the detailed answer!

jimthompson5910 (jim_thompson5910):

sure thing and good luck
