Hi Nivedha,

See there is a concept of Normalisation taken up in TANCET that gives rise to what you call normalised marks. It is basically calculated from your actual marks only. Actual marks are the marks which are allotted for each section according to each correct/ incorrect answer. following formula is used for calculating normalised marks in TANCET:

40 + (10/S) (R– M)

where M= Mean Marks or total marks obtained from the Part I, Part II and Part III divided by 3.

S= Standard deviation of raw marks

R= Raw marks or total marks obtained from Part I, Part II and Part III.

And only Normalised marks are considered for merit list.

i hope it helps.

Good Luck!!
