The results of any assessments that you have completed for the Pilot Apprenticeship remain valid for 12 months. If you completed assessments in the past 12 months for earlier Pilot Apprentice recruitment then those assessment results will still be valid and you do not have to repeat them.
If you have not completed Pilot Apprenticeship assessments in the last 12 months then you have a problem with your account and you will need to contact Jet2 recruitment.
