Here's a breakdown of how your SGPA is calculated -
Semester Grade Point Average (SGPA) is a measure of a student’s academic performance in a given semester. It is calculated as the weighted average of the grade points obtained in all subjects, with the respective credit values as weights. Here's how it is typically calculated:

  1. Grade Points for Each Subject:
    Range Grade Point
    90-100 10
    75-89 9
    65-74 8
    55-64 7
    50-54 6
    45-49 5
    40-44 4
    Below 40 0

  2. Credit System:
    Each subject is assigned a certain number of credits (a measure of workload or importance). For example:
    • A theory subject might have 4 credits.
    • A lab session might have 2 credits.

  3. Formula for SGPA:
    The SGPA is calculated using the formula:

    \[ SGPA = \frac{\sum (\text{Grade Points} \times \text{Credits})}{\sum (\text{Credits})} \]

    where:
    • Grade Points: Grade point earned for a subject
    • Credits: Number of credits for that subject.

  4. Example Calculation:
    Suppose a student has 3 subjects with the following details:
    • Subject 1: Grade Point = 8, Credits = 4
    • Subject 2: Grade Point = 9, Credits = 3
    • Subject 3: Grade Point = 7, Credits = 2

    The SGPA will be:

    \[ SGPA = \frac{ \text{(8 x 4) + (9 x 3) + (7 x 2)}}{ (\text{4 + 3 + 2})}\] \[  = \frac{ \text{32 + 27 + 14}}{ \text{9}} = {\text{8.11}} \]


  5. Purpose of SGPA:
    The SGPA provides a standardized way to evaluate academic performance across different courses and semesters.

Here's a breakdown of how your CGPA is calculated -
The Cumulative Grade Point Average (CGPA) is a measure of a student's overall academic performance across all semesters completed so far. It provides a comprehensive evaluation of the student’s progress and is an aggregate of the Semester Grade Point Averages (SGPAs) for all semesters. Here's a detailed breakdown:

  1. What is CGPA?
    The CGPA is a weighted average of the SGPA values of all semesters. Each semester's SGPA contributes to the CGPA in proportion to the total credits of that semester.

  2. Formula for CGPA:
    The formula to calculate CGPA is:

    \[ CGPA = \frac{\sum (\text{SGPA of each semester} \times \text{Total Credits of that semester})}{\sum (\text{Total Credits of all the semesters})} \]


  3. Steps to Calculate CGPA:
    1. Calculate the SGPA for Each Semester:
      The SGPA for each semester must be computed using the weighted average of grade points and credits for that semester.
    2. Find the Total Credits for Each Semester:
      Each semester has a specific number of total credits based on the courses (subjects) taken.
    3. Multiply SGPA with Semester Credits:
      For every semester, multiply the SGPA by the total credits of that semester.
    4. Sum Up the Results:
      Add up the weighted SGPA values (SGPA × Credits) of all semesters.
    5. Sum Up All Credits:
      Calculate the total credits for all semesters combined.
    6. Divide to Get CGPA:
      Divide the total weighted SGPA values by the total credits across all semesters.


  4. Example Calculation:
    Suppose a student has completed 3 semesters with the following details:
    Semester SGPA Total Credits
    Semester 1 8.5 20
    Semester 2 9.0 24
    Semester 3 8.2 22
    Step 1: Calculate Weighted SGPA Values \[{ \text{(8.5 x 20) + (9.0 x 24) + (8.2 x 22)}}\] \[={ \text{170 + 216 + 180.4}}\] \[={ \text{566.4}}\] Step 2: Calculate Total Credits \[{ \text{20 + 24 + 22 = 66}}\] Step 3: Divide Weighted SGPA Values by Total Credits \[CGPA = \frac{ \text{566.4}}{\text{66}}≅8.58\] Result: The student's CGPA is 8.58.

  5. Purpose of CGPA:
    • Comprehensive Evaluation: CGPA reflects a student’s consistent performance over all semesters.
    • University Standards: It is widely used by universities to measure academic standing.
    • Career Relevance: Many employers and academic programs consider CGPA for screening candidates.
