    I have been associated with COSS since last 10 years. I am an RHCE and RHCA and each of these certifications helped me scale new heights in my career. The best thing about all Red Hat certifications are they are completely practical oriented and you get to learn how to resolve real issues in the classroom.

    COSS has been very supportive in providing utmost care to their students during exam preparation. The intensive exam preparation sessions are really good.

COSS has produced the maximum number of RHCAs in the world and have a highly experienced faculties. The support from the staff is awsome and most importantly they facilitate a good learning environment. Lot of interactive sessions, seminars and expert talks and lab exercises make you confident in cracking the certifications
