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?

If your final has multiple parts and you’ve finished some of them, then you can calculate what you need on the remaining parts. Your current grade should not include any part of your final.

Your current grade is %.

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

Question: My class has a point system. How much is the final worth?

You can calculate how much your final is worth by dividing the number of points in your final by the total number of points.

Including the final, there are points possible.

Your final is worth points.

Question: My lowest test grade is dropped. What do I need to get?

Your overall grade depends on how low your lowest test grades are. If your final replaces your lowest test grade, then tell the calculator that your lowest 1 test is dropped and your final also counts as 1 test.

Your current grade is %.

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

Tests are worth % of your grade.

Your have taken tests already.

Your test average is %.

Your lowest tests are dropped.

Lowest test grade was %.

3rd lowest test was %.

4th lowest test was %.

5th lowest test was %.

6th lowest test was %.

7th lowest test was %.

8th lowest test was %.

Your final also counts as tests.

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.

How would you solve this code...

python program to check if x is a perfect square
import math

# A utility function that returns true if x is perfect square
def isPerfectSquare(x):
s = int(math.sqrt(x))
return s*s == x

# Returns true if n is a Fibinacci Number, else false
def isFibonacci(n):

# n is Fibinacci if one of 5*n*n + 4 or 5*n*n - 4 or both
# is a perferct square
return isPerfectSquare(5*n*n + 4) or isPerfectSquare(5*n*n - 4)

# A utility function to test above functions
for i in range(1,11):
if (isFibonacci(i) == True):
print i,"is a Fibonacci Number"
print i,"is a not Fibonacci Number "

Hello! I currently have a 62.2% (395/650) in my Calc class. I have taken 3 tests so far each worth 100 points with 650 points total available so far in the class. Test 1 i got a 63, Test 2 I got a 60, and Test 3 I got a 59. The Final is worth 20% of our overall grade and whatever percentage we make on the final with replace our lowest test score. Would you be able to tell me what I would have to make on the Final (which in turn will replace the 59 as well) to have a %70 in the class? I appreciate it!

Hey Mr. Roger,
So, I having my next regular exam next week that is worth 22.5% of my overall grade. So my question is what do I need to make on that test to have a B(80%-89%) in that class, as of now I have a 79% in the class from getting at 66% and 92% from the last two tests worth 22.5% of the overall grade. Also, I have my final in that class the same week, so what would I need on the final to have a B in the class. The final in the class is worth 10% of my overall grade. So I need to know what I need to make on my third exam which is worth 22.5% of my grade and also what I need on the Final exam worth 10% of my grade to maintain a B(80%-89%) in the class.

Thank you in advance!

My mental and physical health is deteriorating because of the stress. I have daily stress migraines and emotional breakdowns too. Especially now since it’s right before APs and all the teachers are driving us insane.
Does anyone have any advice on how to reduce stress? Also what are your tips for performing well on an AP with only a week to study (since our teachers give new work up till the week of the test)?

Hello, I have an 84% in my class right now. My final is worth 1/3 of the grade and my 84% is the 2/3 of the grade. I want at least a 70% in the class total so what will I at least need to get on the final?

Thu, 25 Apr 2019 03:11:42 GMT

Hey Roger, so everything except an assignment from the beginning of the year is graded, I'm really close to an A and I was wondering if you could help me out? I currently have a 89.77%

Grade is 6 parts:

1: Tests worth 20% (lowest one dropped), there are 7 of them in total i got: 43/50, 49/50, 47/50, 47/50, 43/50, 47/50, the last one is out of 50 as well.

2: is 40% of my grade and I scored a 91%

3: is 20% of my grade and I scored a 75%

4: is 4% of my grade and I scored a 102%

5: is 6% of my grade and I scored 100%

6: is 10% of my grade and I scored 96.49%

On top l I think there is a .5% extra credit bump (as in if your grade is 99.5 the extra credit will raise it to 100%), but I don't know if we are getting that

With all of this would you be able to tell me what I would have needed to get on this missing assignment to get a 90% / 89.5% depending on the extra credit?

Thank you so much for making this website and answering questions, you're a saint.

My current grade is an 84.45 % because I recently bombed my last test with a 54.69 %.
3 exams (45%)
Homework (20%)
Final (15%)
If there are maybe a handful of homework’s left and the final, do you think I could possibly get a 90 in the class?

Roger: How many tests have you taken so far? And what’s your test average? Try out the calculator mode labeled “I need something else”. It should be able to help.

Hey Roger!

I think that the website that you have created is stunning! I have used it throughout my high school year, and I am looking forward to using it as a freshman in college next year! Through all the sleepless nights, I was able to calculate the score that I needed on tests and finals to skim by with an A. I am now accepted to UC Berkeley!! IDK, but I just felt like thanking you for everything! I guess I wouldn't have had as much motivation to finish High School if it weren't for you!

Thanks again and best of luck in life!!
Jane Smith (lol don't want to use my real name)

Roger: Congrats! I hope you have a great time if you decide to enroll there.

Roger: No, high school is way worse these days.

Tue, 23 Apr 2019 22:46:36 GMT

My current mark is 65%. I have three more tests that are worth 7% each and my final exam that is worth 30%. What do I need to get on each test and the exam to get at least a 90% overall!

Roger: You’ll need to average at least a 114.0% on your next 3 tests and your final to raise your overall grade to a 70%.

Tue, 23 Apr 2019 05:20:35 GMT

I feel like this is wrong. With a 67% right now, and a final worth 20% of the overall grade, thats 20 possible points that could be added to my overall percentage grade. So say, I make a 50 on the test, which is equivalent to 10 percentage points, then I'll bump up to a 77. The calculator said I needed a 136% to make a B...something seems off.

Roger: I think the flaw in your reasoning is “thats 20 possible points that could be added to my overall percentage grade”. If your final is worth 20%, then it has the potential to bring your grade up to a 73.6% (if you ace it) or bring your grade down to a 53.6% (if you score a zero). Note that the range between them is 20%. But it’s incorrect to say that the final can increase your overall grade by 20 percentage points. Does that make sense?

Mon, 22 Apr 2019 15:30:28 GMT

Rogggeeerrr. What would you recommend i do over summer/in my free time as far as software goes, to build my resume. I really want to do some solo projects that will allow me to dive deeper into new topics and gain experience. Are there any project recommendations, or advice you can give to someone for building their resume? I have learned Python and Java so far on my own. Currently learning C in Uni. (im not like super good at any of them) Any specific advice? Any direction i should go? Anything i should study in particular that would make me a useful employee in regards to software/computer engineering. I'm just trying my best out here :( I want to learn more about sorts and different algorithms.

Roger: I spent a lot of time working on side projects, but when I have too much time, I end up getting stuck, because I don’t know what to work on. I think it’d be useful for you to focus on doing things that you actually want to do, like writing a script to help organize your files or writing a chrome extension to modify your favorite website. I’ve brought up silly side projects like these in interviews a lot, and they tend to be more interesting conversation than boring interview questions.
