Hello, chandruvasan!

I can understand your urge to know your TNEA rank. But please be patient, because there is no any source than can provide you with your TNEA rank. You must know tnea rank is published only I the tnea website that too only to the counselling users (only their ranks). But I can give an idea about the calculation of the tnea rank considering cutoff as the primary variable and the gender, age, marks scored in the additional subject and few more criteria.

right now the application itself has not closed so till the application process ends and TNEA publishes the rank you just have to wait.
