Hello!
Yo don't have to bring Class 1 medical for the assessment. You can do it afterwards, if Wizz will select you. Having or not haviing Medical does not affect the assesment.
Type Rating - bonded scheme available.
24-Oct - is not too far from today. Just check yoou status on the career website (don't forget to switch UK/US language on the career website - check both of them)
Best Regards
