You could give Parc in Dublin a call, they have several instructors who could give you a refresher in the 737-200 sim they use.. I've even heard something about a course they run specifically in preparation for the Ryanair assessment - they certainly have at least one instructor involved with Ryanair recruitment.
Out of interest is that as a result of the CAE or SAS appication? If so which? Just making some apps myself.
