It should be noted that written exam pass certificates have a validity of only three years. If your module pass certificates are more than 3 years old when you apply for an NoE or pass your oral exam you will have to submit new pass certificates to the MCA before they will issue an NoE or CoC. The Master Celestial Navigation pass certificate is only valid for 1 year, therefore we recommend that you complete this exam after all others.
