its a royal pain. im originally from NY and went to school out of state, learned next to no compounding. as a result im trying to find a job outside of NY for a year so i can just reciprocate back and not take it.
it is offered twice a year (June and January) and cost a lot. if you fail, you cannot be licensed until you pass (ie fail in june wait till january etc)
there is a review class by one of the professors out of LIU (Dr. cutie). i suggest looking that up, but i may have his name spelled a little off.
