I paid $75 for a three-hour course and got a great deal. The course was very informative (I was fully prepared for the NYS exam) and not too short/not too long.
I can't see why anyone would take the 6-hour course taught by that national company. Also, the course is taught by a New Yorker who is an attorney and a notary. He really knows his stuff and knows how to teach. The time flew by.
I have been a notary for almost a year and owe it to the Sobelsohn School for getting me here.
