Having a cousin who graduated from VTU and read online reviews here’s what I got to know. Firstly, you have to calculate the obtained marks divided by maximum marks obtained from 1 to 8 semesters * 100 to calculate your overall aggregate in engineering.

To calculate your final obtained marks in respective subjects. Final obtained marks will be different in many cases. For example,

• In the first case, if a student is cleared on the 1st attempt, then the 1st attempt marks will be their final marks.
• In the second case, if a student is cleared in the 2nd or 3rd attempt, then the final marks will be their 2nd or 3rd respectively.

Also, according to VTU, they use only 5th semester to 8th-semester 1st attempt marks for awarding the degree or rank's purpose. So, it can’t be considered as overall engineering aggregate marks.

If a company or an exam asks for overall engineering aggregate marks, one should use their final obtained marks from 1st semester to 8th-semester marks.
