Before assigning a grade, the calculator converts marks to a percentage:
The percentage is then converted to a grade using the following scale:
Percentage Range | Grade |
---|---|
95% and above | O |
85% to 94% | A+ |
75% to 84% | A |
65% to 74% | B+ |
55% to 64% | B |
45% to 54% | C |
35% to 44% | P |
Below 35% | F |
The calculator uses a grade point system where each letter grade is assigned a numerical value:
Grade | Points |
---|---|
O (Outstanding) | 10 |
A+ | 9 |
A | 8 |
B+ | 7 |
B | 6 |
C | 5 |
P (Pass) | 4 |
F (Fail) | 0 |
AB (Absent) | 0 |
For calculating the GPA of an individual course, a weighted average is used:
Where:
Example calculation:
Match the final GPA to this table for the course's final grade:
GPA Range | Final Grade |
---|---|
9.5 and above | O |
8.5 to 9.4 | A+ |
7.5 to 8.4 | A |
6.5 to 7.4 | B+ |
5.5 to 6.4 | B |
4.5 to 5.4 | C |
3.5 to 4.4 | P |
Below 3.5 | F |
In this example, 8 GPA corresponds to an A grade.
The SPI/CPI is calculated using the following formula:
Where:
Note: In real-world scenarios, course credits may vary. This calculator assumes a fixed credit of 4 for all courses for simplicity.
Example S.P.I calculation:
For calculating C.P.I:
Must take all course from all semesester into account formula remain same use same formula for used for calculating s.p.i
CPI = Σ(Gi * Ci) / Σ(Ci)
Assume you have 1 courses every semester the following grades and credits:
Using the CPI formula:
CPI = (8 * 3 + 9 * 4 + 7 * 3) / (3 + 4 + 3)
CPI = (24 + 36 + 21) / 10
CPI = 81 / 10
CPI = 8.10
Attendance percentage is a crucial metric in academic performance. It's calculated using the following formula:
Let's calculate the attendance percentage for a student:
Steps:
Attendance Percentage = 90%
Many educational institutions have minimum attendance requirements. For example:
Note: The exact attendance policies may vary between institutions. Students should always refer to their specific institution's guidelines.
These mathematical concepts form the core of the academic performance calculator. The calculator uses these formulas to convert raw marks into grades, calculate Final grade, and determine overall performance indices like SPI and CPI.
