Hello nandini!!

Kindly mention  the name of the college for which you are expecting the college bus. Mostly the college bus will not be available in tirutani. Since the nearby colleges are very few. You will be getting GRT College bhs and Indra college bus. Not any top college buses are available in your area.

For top colleges in chennai refer to the following link below...
