Hello Shamlal Bin Juba it. Thanks for contacting Careers360 and we hope we will be able to answer your query.

The TNEA cutoffs font work that way. The cutoffs are calculated out of 200 and include the marks of Physics, Chemistry and Mathematics which are all converted into 200 and then:

• Cutoff = Maths/2 + (Physics + Chemistry)/4

So, it really doesn't matter how many total marks out of 1200 you got. Only the PCM marks matter. 

I would like to direct your attention to this Careers360 article for more information about the TNEA cutoffs:

Hope this helps you and all the best!
