Hello dear..

TANCET is a very large scale exam, hence two types of marks- Raw Marks and Normalized Marks, are involved in preparing merit list. Raw marks are allotted for each section according to each correct/ incorrect answer. Normalized marks calculated using the raw marks. To find out normalized score from raw score, following formula is used in TANCET exam :
40 + (10/S) (R-M)
where M = Mean Marks or total marks obtained from the Part 1, Part 2 and Part 3 divided by 3.
S = Standard deviation of Raw Marks
R = Raw Marks or total marks obtained from Part 1, Part 2 and Part 3.
After generating merit list, TANCET cut off is prepared

Best of luck
