I did my RHCE from COSS. They are just awsome. I have never seen a training institute who care so much for their students. Every staff member including faculty, management are very co operative. Very good infrastructure, Lab with excellent hardware configuration. Trainers are very cooperative and always ready to help you. The exam orientation sessions really helped me a lot to perform well in the exam

 When I decided to join RHCE training I have enquired most of the institutes in Hyderabad and finally picked COSS, the very first day of my course after looking the lab and other facilities I have realized I have taken a right decision. Thanks to COSS for helping me to get my RHCE certification with 100% score.After getting the RHCE of the Year 2009 award the first thought in my mind was COSS, because without you guys I would not have been dream about this award.  Once again Thank you Guys, looking forward to  join COSS again to pursue RHCSS certification.
