I did some research and i did find that sunbeam and IET pune are good C DAC centers for DAC course, but may not be best. IACSD, Pune seems to at par to sunbeam, pune.
What i found that ACTS, Pune is still the best. Also, MET mumbai, VITA mumbai and YCP mumbai also seems very good institute.
I was surprised not to find so many good words for ACTS, bangalore and ACTS, hyderabad. I am not sure if this is just lack of information or they really not so good.
ACTS trivendram suppose to be good for Mainframe course but again, they are not so well in DAC course.
