Gather your academic records: Collect your academic certificates, mark sheets, or transcripts for the relevant levels of education (such as matriculation, intermediate, bachelor's degree, master's degree, etc.).

Assign weightage to each level: Based on the weightage mentioned in the exam notification, assign the appropriate percentage or marks to each level of education. For example, if the bachelor's degree carries 16% weightage, and you scored 75%, then the calculated marks would be 0.16 x 75 = 12.

Calculate the total academic marks: Add up the calculated marks for each level of education to arrive at the total academic marks. For example, if you have three levels (matriculation, intermediate, and bachelor's degree), and you calculated marks as 10, 8, and 12 respectively, then the total academic marks would be 10 + 8 + 12 = 30.
