Yes, some Instructors on Ostathi may offer free introductory sessions. These are typically short sessions, lasting around 10-15 minutes, designed to help you and the Instructor connect. 

The main purpose of these sessions is for the Instructor to introduce themselves, explain their teaching approach, and for you to discuss your specific learning needs and goals. This allows both parties to determine if there's a good fit before committing to regular classes. The availability of such sessions depends on the individual Instructor's settings and their schedule.
