How does a simple Final Grade Calculator Work

As you have seen in the above image that the current grade percentage was 82% and targeted was 85% on the finals and the weightage was in the final exam was 30% so you need to score 92% to achieve targeted score of 85%.

You can change final exam weightage according to your school, college, university grading criteria for instance your organization give 40% weightage of final exam in total grade and your current% is 69 how much you need to achieve 85% given below.

The above mentioned calculator was the simplest final grade calculator introduced in 2009, eventually from the feedback in summer of 2013, there were several additional extensions added in final grade calculator, which are the following mentioned bellow:

Overall grade after final exam

A fresh calculator was formed for those who have an evaluation of what they will score on final exam and the want to estimate the overall grade after having the estimated final score. If you enter the required data,

it will calculate the total grade including the final exam.

The formula used in this calculator is given below:

• CG = Total grade earlier the final exam
• FG = Score, Estimated score on final exam
• w = Weightage of the final exam
The overall grade = (1 − w) CG + wFG

As you have guesstimated, this is basically the product of detaching DG (desired grade) formula for the original calculator.

Grade required on the final test

This calculator was designed to calculate what to score in your final test, by giving the following
data, it estimates the minimum% grade needed on the final exam that sums as part of the
Regular “test classification”.

• CG = Current Total grade
• DG = Desired Total grade
• w = Worth of the test in category
• nT = Number of tests taken
• AS = Average score in the test category
• tF = The final test is worth this number of test- equivalent units

This calculator presumes that the only unevaluated category is the test category. It also assumes that all tests are equal in weightage, with the exclusion of the final exam which is weighted a standard test-equivalent unit.

If all the test are not of equal worth, even then this calculator can still be utilized in a roundabout way. The variables nT and tF are always used in combination, such that only the ratio tF / nT + tF needs to be accurate. Changing nT with the number of total possible test points available and tF with the number of test points on the final test would also yield a correct outcome.
To get the answer we first calculate helping variable τ:
We let τ = 0 if w = 1
CG – W (AS) / 1-w if w <1

Where variable τ shows the mean grade of the other test categories. These classifications have no impact on the final test (denoted as f). Following the formula:

DG ≤ (1 − w) τ + w (AS (nT) + f (tF) / nT + tF)
Detaching f, we get: f ≥ ((DG − (1 − w) τ) (nT + tF) – w (AS) (nT)) / w (tF)
When w <1, this simplifies to: f ≥ (DG − CG + w (AS)) (nT + tF) – wASnT / wtF
When w = 1, the expression becomes: f ≥ DG (nT + tF) – (AS) (nT) / tF

This formula forms alike to the original calculator's formula, because if tests are the only remaining category, then the final test can be treated as its own unevaluated category with weight tF / nT + tF.

Similarly, additionally more features were added in evaluating final grade for different categories as diverse institutions and organizations have different grading criteria like some have multi-day final exams, where some of the score from test assignment or quizzes are already graded, but none of the grades have been added into the total grade yet,

so a specific final grade calculator is designed for this purpose forming new formula. Then final grade calculator was updated for the point system, features like if student test drops and final score weightage increases what is required.

In 2018 the final grade calculator is upgraded and in the form of a questionnaire user are asked about their required data needed to calculate and evaluate what they want.
