How do I get admission into the B.Tech program at Madras Institute of Technology?

My senior from school who used to be a student of Madras Institute of Technology told me that he got admission through the Other state Quota. There are other quotas as well. For example:

• TNEA: Only those students who have completed their 10 (+20) Tamil Nadu can apply through this entry.
• Other state Quota: Students who have proof of residence of other states and completed their 10 (+2) from some other state can make use of this quota for their admission.
• NRI & FN quota - For making use of this quota, candidates must have passed their 10 (+2). Passing from an English medium school or having proficiency in English is compulsory for candidates. They should have passed in all subjects and scored a minimum of 50% aggregate in Mathematics, Physics and Chemistry put together in qualifying examinations.
• Industrial Quota: Parent(s) and/or guardian(s) should have an industry.

In addition to the above quotas, there are also government quotas, governor quotas, Vice-Chancellor quotas which are probably getting letters of recommendation from the governor, Vice-Chancellor, and other high-ranking officials in the government.
