See if you belong to outside Tamilnadu then the eligibility will be different and you will be considered only for private colleges. However if you are a non-Tamilian who has studied in Tamilnadu as the brochure says" Other State candidates who have studied VIII, IX, X, XI and XII Std. in Tamil Nadu are eligible to apply. They need not enclose “Nativity Certificate”, you are eligible for TNEA admissions. Now I would first like you to clarify this point then I can be help better.

So please let me know if you are planning to apply as an outside state candidate or whether you are a non Tamilian who has studied in Tamilnadu.
