Dear Mr.Chen,
I am taking environmental science in a community college. I am in grade 9
Tests worth 68% of my total grade

Currently, I have a 83% total and I took 50% of the test
In order to get 90%+ in my final garde
What % at least do Ineed to get on my remaing test?

Get back to me soon! Thank you :)

Roger: The answer depends on your current test average. But assuming the other 32% of your grade does not change, you’ll need to raise your test average by at least 10.3 percentage points to raise your overall grade to a 90%. Hope that helps!

If I have a 80, 85, 77,78, 96 ,100 & 100 as 80% test grades, and 24 100s for hw grades (10%) and 22 100s for participation (10%), do I have an A in that class? Or at least a high B?

Roger: Your overall grade should be 90.4%.

Thanks so much for your help Roger. I really appreciate you helping people. I am absolutely grateful I found this calculator while scrolling absentmindedly through the web. 😁 I hope you have a nice day/afternoon/night and thank you again.

Roger: Thanks, and you’re welcome!

Hey Roger, I have a question that I ask that you please help me in: The total attendance for all of a baseball league in 2012 was about 7.5 x 10^7 fans, while the attendance for the Tornadoes in 2012 was about 1.5 x 10^6 fans. About how many times more was the attendance for the entire baseball league than the attendance for just the Tornadoes.

Roger: 50?

My average class grade in English is an 90.71. I made a 67 on a test that was worth 65% of my grade. Please tell me what my averge in English will be now.

Roger: It depends on how many tests you’ve taken so far and what you scored on them. Also, what’s the other 35% of your grade made of?

OKay so i have a 94% in my biology class, and i am taking my midterm today and my midterm is worth 10% of my grade. What do i need to make on the midterm to have a 96 final grade?

Roger: It depends on how much of your coursework you’ve completed so far. For example, if your “94%” overall grade represents 40% of your coursework, then you’ll need to score at least a 104% on your midterm to raise your overall grade to a 96%.

Oh one more thing. My weight achieved so far without the last exam is 36.3/60. My dosage exams weight achieved is 32.30 and my homework is 8.4/10. Again what would I have to make on the last exam to get 74.5/100.

Roger: I don’t quite understand. So if you get a full score on your last exam, then does your “weight achieved” rise from 36.3 to 46.3? What do you mean by “dosage exams weight”?

I have a 68.5 average and I have to have a 74.5 to pass the class. I have one more test left out of 5 and all together they are worth 60% of my average. If the test are weighed out of 15 points what do I need on the last test to pass the class ?

Roger: What’s your current test average? What do you mean when you say that your tests are “weighted out of 15 points”? Also, try out the calculator mode labeled “I need something else”. It should be able to help.

Hello
I have just completed my pharmacology I had to receive an overall mark of 50% overall , I received a mark of 49.05%
So I am .95% of a mark of passing the subject .. can I dispute this mark as .95 is not even one mark .

Hi Roger, I would really appreciate your help in calculating my final grade so I can know if I need to retake my final or just let it ride. My final exam is 60% of my grade, the mid term is 25% of my grade and quizzes are 15% and I need a 70 to pass the class. I got a 61 on the final, a 75 on the midterm and a 90 on all the quizzes. Would this be a passing grade of 70? Thank you so much! Sam

Roger: Your overall grade should be a 68.85%.

Hi can you please help me? So my mark in Chemistry is currently a 65% (horrible I know). My final exam is in a few days and it is worth 30%. Ive been studying hard, but a random question just occurred to me just now, what if I completely bomb the exam and got nothing right, what would my final mark be? Thank you! I hope you can get back to be ASAP.

Roger: If you score zero on your final, your overall grade should drop to a 45.5%.

Thank you very much!

Roger: Check out this blog post.

Thanks Roger

Lol, the teachers at school really hate you (because they think if the calculator says we need to get a low score to pass, we won't study for their class [which is true lol])
but the students in all of my classes worship you, because you are the one true savior of our grades
thanks for helping me pass spanish, algebra 2 honors, and bio :,)
i'll be back next school year, as will everyone else! lmao rogerhub becomes the most popular website when it gets near finals

Roger: Haha. Is it a matter of pride to make students study? Maybe abolishing fixed grade thresholds would eliminate a lot of these problems. Some of my college courses didn’t set the letter grade thresholds until after the course was over.

Hey Roger,

Your website has really inspired me to take on some projects. I'm working on a significant robotics project right now, but I want to make a website like yours! I have made a game in raw JavaScript: laserhell.site11.com. I plan to improve it a lot. I also have some ideas for tools I really want and really want to make that are similar to your final grade calculator. Thanks for inspiring me, I think I will make one website with all of these things on it. Do you suggest I use WordPress? I think WordPress seems good if its themes and whatnot take care of the art side of it.

Best,
Ben

Roger: Glad to hear! I used to use WordPress, but don’t any longer. I think that unless you want to start a blog, WordPress creates more headaches than it’s worth. If you’re only making JavaScript apps, I’d recommend using a static site generator and a free web hosting service like GitHub Pages.

So I have a 83.17 in my Geometry class, and my final is worth 10% of our grade. But my lowest test grade is being replaced with a 89, and my lowest test grade is a 62/100. So what do I need to get on the final to maintain a B?

Roger: It depends on how much your tests are worth, how many tests you’ve taken so far, and your current test average. Try out the calculator mode labeled “I need something else”. It should be able to answer your question.

I am freaking out. I have a 60% in history and I only have 4 quizzes, a unit test, and a final exam. If I got A's and B's on all that I listed before the end of the class, would it bring it up enough to have an overall of 85%??

Roger: Sounds unlikely. The exact answer depends on how much those grades are worth. Try out the calculator mode labeled “I need something else”. It should be able to help.

Hey Roger!

My tests together are worth 40% of my grade. My average test grade is 75, my lowest score is 60. The final is worth 10% and our lowest test grade gets dropped. I also have a second practical. Together they are worth 25%. I got a 91 on the first one. I have a class average of 85. I would like a 90 in the class. What do I need to get on my second practical and final to get a 90? Sorry, I know this was a lot!

Roger: The answer depends on how many tests you’ve taken so far. Try out the calculator mode labeled “I need something else”. It should be able to answer your question.

Fri, 12 Apr 2019 01:56:31 GMT

Roger,
you should add a function to save the class setup in advanced mode so you can change the category grades each time you have a new grade. that way you dont have to keep setting it up every time you get a new grade. just a suggestion!

Roger: Thanks for the feedback! The calculator purposefully doesn’t have any kind of persistence between sessions right now. There are probably privacy implications around storing student educational records in the United States. Storing them in your browser is an option, but introduces potentially unintuitive and confusing behavior. I’ll look into whether it’s possible to implement something like this safely, but I hope this provides some insight.

hi roger, im really desperate lol

i have a 91 in calc but i recently just recived a real F on the most recent test. tests are worth 50% of our grades and i have one chapter test left before the final. finals are worth 15% of our grades.

how much will my grade drop and what could i get on the next test and the final in order to get myself back up to at least a B?

thanks roger :(

Hi roger! So i’m currently at a 90% and I’ve only had one test and that test i got was 4/12. And that 4/12 is worth 30% of my grade. How much would that 90% go down by?

Roger: It depends on how much of your grade is accounted for so far. For example, if your “90%” grade represents 50% of your grade, then your overall grade should go down to a 68.75%.

My grade right now in Biology is a 65.65%. I need a 70% to pass the class. I still have 2 test left and the final exam. Test 1 I got a 48%, test 2 I got a 50%, and test 3 I got a 66%.
All 5 total test are 50% of my total grade for the class (100%).
The final exam is 10% of my total grade.
What are the lowest test scores I can get on test 4, 5, and final exam in order to pass the class with a 70%?

Roger: You’ll need to average at least a 72.8% on your 2 remaining tests and your final exam to raise your overall grade to a 70%.

My average grade for both semesters is 45.8 perfect I need a 50 to pass. The final exam is only added to the average grade and nothing is taken away from the 45.8 (essentially it’s what you get without doing the exam) I scored a 33.333 percent on my final worth 20 percent. How much will my mark go up?

Roger: That sounds a bit strange, but I suppose your overall grade should go up by 6.67 percentage points to a 52.47%.

I get to drop one assignment of choice with the lowest score but I can’t decide which will have more of a positive impact on my grade.

Assignment #1 falls into the “essay” category weighted at 40%. My current average is 96%, my lowest score is an 87% and there are a total of 16
Assignments in that category.

Or

The other option falls in the “test” category weighted at 35%. My current average is 95.58%, my lowest score is a 70% and there are 6 assignments.

Which assignment should I drop that would be beat for my grade?

Roger: I’d say that dropping your lowest test grade is almost certainly more helpful. If you want more details, try out the calculator mode labeled “I need something else”. It should be able to answer this question.

If anyone else needs to calculate what percent they'd need on their final plus the final grade replaces the lowest test score you need to calculate

P=percent needed on final

(%final is worth of final grade x P) + (% other sections are worth x grade in those sections) + (percent test section is worth) x ([(% gotten on previous tests x points that test was worth) + (P x points the lowest test grade was worth)]/total points in test section)

.... I think

Roger: By the way, the Final Grade Calculator already handles this. Try out either the option labeled “My lowest test grade is dropped” or the option labeled “I need something else”. Both of them should be able to answer this question.
