Which is the best coaching Centre for IES (civil engineering) in India?

One of my cousins attended ACE Academy for IES coaching. He had a great academic experience. You should do your research about the institute before joining. Gather information about the faculty members, teaching methodology, quality of study material, accuracy of their test series, and their current ranking among the coaching institutes. My cousin shortlisted ACE Academy by judging these parameters.

Faculties:

• The faculty at ACE are all mostly from IITs, some are even IEC qualified and most of them are ex-IES officers. ACE academy has been constantly producing top rankers in civil engineering and also other disciplines. 
• The faculties offer detailed notes and study material that are quite helpful for preparation. Also, they teach useful short-cuts and tricks which have proved to be extremely helpful in saving time during the examinations. 

Practice Sets:

Practice sets are provided regularly to check the comprehension and analyzing capability of the student.

ACE coaching is certainly one of the top recommended coaching centers for IES. Even if you are unable to travel and attend the regular classes, there are options of getting notes via post. These notes are quite concise and very easy to understand.
