Hello Nusret
Sounds good, doing ENCORE will get you up to speed so that you can develp the momentum necessary for CCIE.
As Rene often states, the content on NetworkLessons helps trainees understand the topics that will be faced on the label for CCIE. The content here may not be enough, so it is recommended that you use workbooks like those available from INE or Cisco 360.
A workbook, in combination with the explanations on NetworkLessons should give you a solid foundation on which to build and achieve your certification.
I hope this has been helpful!
