    Administration training

    Good coaching and well support I have received from COSS - Complete Open Source Solutions, Dilsukh Nagar. I have taken the admission in this institute for doing Linux Admin training 10 months before, due to some reason I have not joined at that time. But now, I have joined this institute again on that old fess. Teaching Method, class atmosphere, study materials, and infrastructure all are good. I am happy to join this institute.
