How many lessons do I need to get a Drivers Ed certificate?

I'm in New York State, just got my license. However, I need to take drivers ed so I can drive after 9. This one driving school offers individual lessons, do you think they'd give me that certificate after just 1 lesson? That way I save boat loads of money. Otherwise a 7 lesson plan is like 350 bucks.|||Only the driving school can answer your question, not random strangers on Yahoo answers.
