Hello Priya, Greetings!
Let me help you.
The best way to find a suitable coaching for UPSC preparation is by checking the attributes like past results of the coaching, faculties experience, infrastructure of the coaching, reviews of that coaching from the ex-students and teaching methodology.
Some of the best IAS coaching in Chennai are:
1. ALS IAS Academy
2. ALS Satellite Education Centre
3. Officers IAS Academy
4. Shankar IAS Academy
5. Ganesh's IAS Academy
Thank you, hope this helps.
