Greeting Aspirant,

Calculating the TNEA marks is Very easy. You can calculate by seeing the steps below:

• Maths Marks will be same
• Divide Physics marks by 2
• Divide Chemistry marks by 2
• The result you get by adding is your TNEA marks.

Example: Maths-80, Physics-76, Chemistry-94

• Divide Physics Marks by 2 (76/2=38)
• Divide Chemistry Marks by 2 (94/2= 47)
• Maths Marks will be same (80)
• Add all the Marks (38 + 47 + 80 = 165)
• So in this example we got TNEA marks as 165 out of 200

Hope My Answer Helped You.

Best Of Luck For Future.
