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.
