dear aspirant,

the total  cut off marks  will be calculated for engineering colleges they should take only 3 subjects(mathematics,physics,chemistry) to calculate each subject contain 200 marks and total 600 marks

mathematics total 200 cutoff 200/2=100

physics total 200 cut off 200/4=50

chemistry total 200 cutoff 200/4=50

engineering cutoff =200/200

for example if you got these marks :

mathematics total 200 marks and  you got 197 marks cut off calculation is 197/2=98.5

physics total 200 marks and you got 173 marks cut off calculation is 173/4=43.25

chemistry total 200 marks and you got 176 marks cut off calculation is 176/4=44.0

hope this information may help

thank you.
