Study path

Five steps from first look to exam day

  1. Know what's on the exam

    Read the Network+ objectives decoded into plain English, with the exam traps for each domain.

    Open Network+ Clearances ›
  2. Take a baseline drill

    Drill 1 is free: 75 questions with breakdowns. Your score shows which domains to hit first.

    Start Drill 1 (free) ›
  3. Learn the concepts

    Work through the lessons and posts for the domains you missed, starting with the heaviest-weighted ones.

    See the lessons ›
  4. Prove it in a lab

    Run the PBQ-style simulations. They're scored on the final state, just like the real thing.

    See the labs ›
  5. Drill to exam speed

    Work through Drills 2 to 8 until you're consistently above 85% under exam time. Retake anything under 70%.
