Where can I get a recommendation for Loyola College in Chennai?

The simplest option is to meet the fathers there and state your case, but this is difficult work for students because they expect you to come and meet them multiple times and wait hours. 

They will basically put you to the test by seeing how much you want the seat. This requires patience, but it is the best-case scenario for securing a seat if you do not have the high markets required or the necessary contacts. 

Bring one of your parents with you; it will be very helpful.
