To convert your 10th-grade CGPA to a percentage, you can use the following formula: Percentage = (CGPA - 5) * 9.5 Here's how to calculate it step by step: Subtract 5 from your CGPA. Multiply the result by 9.5. For example, if you have a CGPA of 9.0: Percentage = (9.0 - 5) * 9.5 = 4.0 * 9.5 = 38.0% So, a CGPA of 9.0 in 10th grade is equivalent to 38.0% in terms of percentage.
