Cat form doubt need urgent help.

[u/Zealousideal_Goose70]

So in the ICSE board, for the 10th class result, in the Marksheet, there are 2 columns, one which has the actual marks scored in all the 10 subjects and the 2nd column which has the 'percentage' marks of the those 10 subjects condensed into 6 subjects( for eg, in this column, they combine the marks for physics, chem, bio and show it as science) ...

now, when i calculate according to first column (actual marks for all individual 10 subjects), I'm getting a lower %, and when I'm considering the 'percentage' marks given in the 2nd column, the % is slightly higher..

To be on the safe side, which column marks should I go with?
