    Questions for the Experienced

    you can use Anki software for retaining your knowledge http://ankisrs.net/ , i just came to know this software at the end of my 5+ years journey. If i know it in beginning i have cut short this journey at least 1-2 years shorter. Second its all about basics, CCIE lab is 50% basics.
