Academic: Passing score in all academic subjects with minimum 45% average marks in Mathematics, Physics and Chemistry put together in Class 12 for General Category and 40% for all other categories.
Vocational: Passing score in all vocational subjects with minimum 45% average marks in Mathematics, Physics, Chemistry and Vocational Subject put together in Class 12 for General Category and 40% for all other categories. Prescribed vocational subjects for Engineering courses are given below.
The selection of candidates for engineering courses will be based on the marks obtained in the relevant subjects reduced to 200 (Mathematics:100, Physics + Chemistry : 100) in the qualifying examination.
For Engineering, Tamil Nadu Engineering Cut off = Maths + (Chemistry / 2) + (Physics / 2)
Improvement marks improvement marks obtained by the candidates including Other State candidates will not be considered for cut off calculation.
Mark Normalisation
Marks obtained by the students conducted by various Boards such as CBSE, ICSE, other state boards, etc shall be normalised with the marks obtained by the students in the same subject of Tamil Nadu State Board based on the highest marks scored in each board examination.
If the highest mark secured by the Tamil Nadu state board student in Mathematics is 100 and the highest mark secured by a student of ICSE Board in Mathematics is 90, then highest marks in each board will be equated to 100.
If a student of ICSE Board secures 60 marks in Mathematics when the first mark in Mathematics in the same Board is 90, 60 marks will be considered to be equal to 66.66 marks.
(60/90) ∗ 100 = 66.66%
After normalisation of marks in Maths, Physics, Chemistry subject in the +2 examination conducted by various Boards, the cut off needs to be calculated.
In general, few students from CBSE board takes 100 in all relevant subjects and normalisation was not done for last few years.
