Question: I took the final. What’s my overall grade?

Since you’ve already taken your final exam, you can now calculate your overall grade.

Your grade was % before.

You got a % on the final.

Your final is worth % of your grade.

Question: My final counts as a test. What do I need to get?

If your final is in the “tests” category, then your overall grade will be affected by your current test average and how many tests you’ve taken so far.

Your current grade is %.

You want (at least) a % in the class.

Tests are worth % of your grade.

You have taken tests already.

Your test average is %.

The final is worth tests.

Question: There are 2+ parts in my final. What do I have to get on them?

Your final is also worth % of your grade.

How does this work?
Most class grades are made up of several categories: homework, classwork, tests/quizzes, and the final exam. Usually, each category is worth a percentage of your overall grade. But because your final exam isn't scored until the very end, it isn't included when calculating your current overall grade. Instead, all the other categories are scaled up to consume the weight reserved for the final exam. Therefore, you can calculate the minimum grade you need to score on the final exam using the formula:

Required = (Goal − Current × (100% − Final Weight)) / Final Weight

See the formula sheet for an explanation of this formula and other formulas used in this calculator. It's not rocket science, it's just math! You could, of course, do this on any calculator, but you're here on RogerHub because it's cool. (:

I need more help!
Try one of the different calculator modes listed above. The advanced mode handles many different kinds of situations, such as:

  • If you have more tests and homework before the final
  • When your final counts as a test grade
  • Dropping the lowest test grades
  • Makeup assignments or test retakes
  • Extra credit
  • Missing assignments

If none of those options answers your question, feel free to ask your question in the comments section below.

I recently got my worst grade of an F back to a 63% and on an old test from two weeks ago, I used a few things from another person's test and got an F on the test for it, it's worth 43% of my grade and wanted to know how much this will affect my overall grade of 76%

Our passing grade 75%, every quiz and exam, if you score between 70-75, you're eligible for a rewrite. If btw 65-70, repeat the entire semester. If below 60, expelled,or shall i say.. asked very nicely, to take a break and come back when you're ready.

Quizzes are mostly 2-10%
Midterm 15-30
Final30-40 (yes, it's ridiculous. I know)
And then our random assignments

hey there

roger sir

it's me

over here,

oui, monsieur

yeah, it's that one girl

yes, it's her

the one who keeps


about life

and its miseries

the one who keeps


to unravel its mysteries

the mysterious evil

that plague the earth

also known

as stupidity.

Wed, 20 Feb 2019 05:20:25 GMT

hey guy

who commented below

yes you

the one who pleaded

but has not not succeeded

to get roger's attention

(yes, for the billionth time, it's you i've mentioned):


if that is your

most urgent request

consider yourself lucky

not to have all this stress

things weighing you down

so hard it hurts your chest

consider yourself lucky

and consider yourself blessed.

Hey Roger,
Wed, 20 Feb 2019 02:49:29 GMT

guys i checked my grades online

and i saw that i got a really bad grade on something

but i was so sure i did everything right


and it was a really easy assignment

and im really upset

and i hate school now

i used to love school and look forward to it

but because of this stupid teacher

i will never see school the same way again

school is pain

and i have very low tolerance for it


to the student who once thought

she could be anything

do anything.

because now she realizes

that there's no point trying to change the world

because it's full of idiots

and they don't deserve my help

Right now, I have a 87 in chemistry. Quizzes are worth 20% and i have had 4 quizzes, my average being a 81.25% in that category. Tests are worth 50% and i have had 3 tests, my average being a 86.33% in that category. Homework is worth 10% and i have had 13 homework assignments, my average being a 100% in that category. The final category is the final exam, that i have not taken yet, which is worth 20%. My teacher is offering to put in a 100% as a quiz grade if we do an extra credit assignment. The only thing is that the extra credit assignment is very tedious and boring. I want to know how much that 100% could bring up my test grade, so i can decide whether it's worth it or not. I am trying to get an A in the class. Thank you.

Hi I have a 83% in my AICE Eng Lang Class and I got a 100% on my project that was worth 25% of my grade. How much will my grade go up in that class? Plz help me!!!

Roger: Is your project worth 25% of your grade by itself? Or is part of a “projects” category that’s altogether worth 25% of your grade? Try out the calculator mode labeled “I need something else”. It may be able to help.

I'm so worried. I'm retaking MAT 143 because I have a difficulty with math, and I accidentally forgot to do some work for it, as well as not been able to do too well in it so far. I really don't want to retake this again and have wasted my money. I know it's still early-ish in the semester (started Jan. 5th) and I can still bring my grade up but... Please pray for me.

Why are you running

Hi Mr. Chen. My name is Koki and I love your calculator. I love it more than my left kidney. It is my second favorite hub of all time, second to only github. As a side note, I like to program and upload Japanese Manga stories and commit and push them to github. You should go check it out. I’m actually somewhat of a hub connoisseur myself. My schoolmate acquaintances don’t call me “Kokihub” for nothing. I only eat food from GrubHub, and I actually get my car insurance from there as well. I have a list of hubs I use on ListHub. That’s how hardcore I am. I happen to even know that MineHub isn’t actually my hub, but a hub for mining and resource collection. I actually work at a hub, but I can’t say which hub because it’s classified. Call me James Bond. Tire experts are created by me, for me.

Roger: I originally “RogerHub” because of USB hubs.

The projects are due Monday and I have TWO to do since my teacher wants detail on the building. Also my teacher hasn’t told me about re tests yet, hopefully theyre before the report card.

Overall there are (4 Unit Exams..55%)
(5 weekly Quizes 5%.{1%each}) and (1specialty exam HESI...20%)....
What do I need to get on the rest of my test to get up to a 78% to pass

Roger: What did you score on your past exams and quizzes? What’s the other 20% of your grade made of? Try out the calculator mode labeled “I need something else”. It should be able to answer your question.

i am a senior and all i want now is the sweet embrace of graduation. i used to use this calculator during my junior year because i was constantly stressed and let my grades define my self worth. kids, don't let grades make or break your confidence in yourself. you can have a great GPA and a poo personality. or vise versa i guess but who cares. just dont let one thing control who you are

Wed, 06 Feb 2019 04:35:01 GMT

i was just scrolling through the comments, and i found one that was basically saying that we complain a lot and it's our fault our grades are bad and all that jazz. idk why, but it kinda pissed me off so here i am
first off, it was stated our full time occupation is a student so grades below 95% is bad.
a lot of students aren't just students. kids participate in sports, clubs, extracurricular activities, and some even have jobs. most of these things don't really work with your normal eight hour school days so more often than not you aren't left with a lot of time to do school work. this doesn't even account for the fact some kids take ap and dual credit courses and honestly, i could go into a whole other rant on that by itself.
secondly, not every school and teacher is the same. some teachers genuinely suck and probably shouldn't be teachers in the first place so it's left to the student to do a lot of self teaching. even then, some support systems offered at school is awful and rarely ever help the actual kid out.
lastly, i'm assuming most adults nowadays wouldn't even really be able to understand what the heck is being taught in modern day classrooms anymore. nearly every adult i've asked who isn't an educator has trouble with even the simplest things so it's hard to take someone who can't even understand how to find corresponding angles in a triangle seriously.
sorry for the rant, the comment just really annoyed me and i wanted to get it off my chest.
