Can you post how you prepared for CKS ? Is going through course is enough for certification ?
Basudeb Tripathy:
I believe Its enough, I did the same, try to focus on the concepts on each topic, next Mock exams, Also there are CKS challenges questions ( 4 questions ) ,And next killer.sh as much as possible.
