Failed CEH (Certified Ethical Hacker)? Here's Your Recovery Plan

Pro tip: You do not repeat the eligibility application when retaking; the original approval carries. Refunds are not issued for failed attempts. EC-Council strongly recommends candidates who fail a third time attend official hands-on training covering the certification objectives, and reserves the right to revoke the certification status of anyone who attempts the exam outside this policy.

• Assuming the pass mark is 70 percent
  EC-Council does not use a fixed pass mark. Cut scores are set per exam form and cert.eccouncil.org publishes a 60 percent to 85 percent range. Plan for the 85 percent form, not the 60 percent one, because you do not get to choose which form you receive.
• Studying the 20 course modules instead of the nine blueprint domains
  Blueprint v5.0 groups the modules into nine scored domains with fixed question counts. Sniffing, social engineering, DoS, session hijacking and IDS evasion together carry 30 of 125 questions under Network and Perimeter Hacking. Weight your revision by the blueprint, not by module count.
• Skipping cryptography, wireless and cloud because each is only 5 percent
  Those three domains carry 18 questions between them, more than the entire web application domain. All three are recall-heavy and cheap to secure. Losing all 18 can be the difference on a high cut score form.
• Applying for eligibility the week you want to test
  EC-Council says application processing averages 5 to 10 working days once verifiers respond, and the approval is valid for 3 months. Start the application before you finish studying, not after.
• Letting the exam voucher expire
  EC-Council vouchers are valid for one year from release. An extension costs USD 49 for 3 months or USD 99 for 1 year, and an already-expired voucher can still be extended for a year at USD 99 by writing to EC-Council.
• Learning tools without learning their output
  CEH questions show you a fragment of Nmap output, an enum4linux dump or a Wireshark summary and ask what happened. Run each tool once in your own lab and read the output format, because recognising a half-open scan signature is a different skill from typing the command.
• Ignoring OT and SCADA content in the mobile and IoT domain
  Blueprint v5.0 splits that 12-question domain into 6 mobile questions and 6 IoT and OT questions, and OT is listed with its own concepts, attacks, methodology and countermeasures bullets. Modbus and DNP3 lack authentication by design, and that fact alone answers several question styles.
• Answering methodology questions out of order
  Many items hinge on sequence: footprinting before scanning, scanning before enumeration, enumeration before vulnerability analysis, then gaining access, escalating privileges, maintaining access and clearing logs. If two answers both look technically correct, the sequence usually decides which is right.
• Choosing the most aggressive answer
  CEH is written from the perspective of an authorized tester working inside a signed scope. Where one option exceeds the stated authorization or skips written permission, it is wrong regardless of technical accuracy.
• Forgetting the certification does not stay valid on its own
  CEH sits under the EC-Council Continuing Education scheme: 120 ECE credits per certification within a three-year window, plus an annual continuing education fee of USD 80 for members holding at least one ECE-covered certification. Credits are logged in the Aspen portal.
