CGPA Calculator
Enter the grade points shown by your institution. Grading scales and rounding rules vary by university.
| Course | Credit hours | Grade points | |
|---|---|---|---|
Formula: GPA = sum(grade points × credit hours) ÷ total credit hours. Updated CGPA combines previous and current quality points.
The final exam weight is assumed to be the remaining course percentage.
Advanced local scientific calculator: DEG/RAD, sin/cos/tan and cot/sec/csc, inverse and hyperbolic trig (including inverse hyperbolic), roots, powers, logarithms, exponentials, factorial, modulo, reciprocal, memory and previous answer. Use function syntax such as sin(30), asinh(1), sqrt(9), log2(8). Safe expression parser; no eval().
Dynamic Mathematical Graphs
Plot y = f(x), trigonometric curves, and parametric 3D curves x(t), y(t), z(t). Graphs update as you change the function, ranges, angle mode, or 3D rotation. Use explicit multiplication such as 2*x.
2D diagrams scale as dimensions change. 3D previews are schematic; calculated area, perimeter, surface area and volume use standard formulas.
