Delco --
Your instructor should have given you a brief on what to expect in the check out dives. And, quite frankly it's a bit difficult to say with certainty what skills you will be asked to perform and when as it does vary a bit from agency to agency and instructor to instructor.
That said... as a rule... you should expect at a minimum to have to do snorkelling skills such as surface swims, head first and/or feet first surface dives, mask and snorkel clearing, etc.) in addition to SCUBA skills such as mask clearing, regulator clearing, regulator retrieval, controlled ascents and decents, either an emergency swimming ascent and/or emercengy buoyant ascent and at an air sharing ascent.
