According to my friend studying there, Madras Institute of Technology is one of the reputed engineering institutes. Getting admission in a B.Tech program is somewhat difficult. Here are some of the ways you could get admission.

1. TNEA: This method is applicable only to the students who have completed their 12th from Tamil Nadu.
2. Other State Quota: If you belong to another state other than Tamil Nadu and have completed your 12th outside of Tamil Nadu can apply through this entry by showing their residence proof. 
3. NRI & FN quota: Students who are children of Indian Workers in Gulf Countries (CIWGC) or are Non-Resident Indians (NRI) or are Foreign Nationals can apply through this entry. The students must have studied from an English medium school or should have decent proficiency in English. 

There are also some other ways like Government quota, Governor quota, Vice-Chancellor quota through which students can get admission. By getting a letter from higher government officials like the Governor or Vice-Chancellor, will secure your admission.
