hello lavekushtrivedi,

You have mentioned about TNEA marks. For your clarification, I must say there is nothing named TNEA marks officially. But I take an attempt that you are stating about your Cutoff marks.

Here is how to calculate cutoff marks for TNEA application:

1. Collect up your marks in Mathematics, Physics, Chemistry.
2. divide obtained mark by total marks for respective subjects
3. then follow the formula below

the cutoff marks= (quotient of maths*100) + (quotient of Physics*50) + (quotient of chemistry*50)

According to the marks, you secured

maths =85/100 = 0.85

physics=88/100 = 0.88

chemistry=83/100=0.83

cutoff mark = (0.85*100)+(0.88*50)+(0.83*50)

=85+44+41.5

=170.5.

your cut-off mark is 170.5.

but we cannot say sure about your rank. because the rank varies year to year based on the marks scored by every student who applied for the TNEA councelling. so kndily wait till the application for closes and the rank will be published later.
