Gradation Calculator

This updated version focuses specifically on the two types of grading scales you requested: the Standard Letter Grade (A-E) and the Sub-divided Grade (A1-E), which is commonly used in CBSE and international school systems.

Changes implemented:

A to E Scale: This is a broad 5-tier system (A, B, C, D, E).

A1 to E Scale: This follows the 8/9-point grading system (A1, A2, B1, B2, C1, C2, D, E).

Refined Thresholds:

For A1-E, it uses the standard 10-point gaps (91-100, 81-90, etc.) with 33% as the passing limit for 'D'.

For A-E, it uses wider gaps suitable for general performance marking.
