Do a google search for NY bar exam/NJ bar exam and you should find the bar examiners website. I don't know anything about NY/NJ but I'm planing on doing CO and WY bar, and the way it works (from reading thier respective websties) is you do an applicantion to both. The CO exam is two days before the WY exam, so you take the MBE on one day and the CO essay exm on the other day, then drive to WY and take thier essay on the third day. WY uses your MBE scores from CO. I'd bet it very simular in NY/NJ assuming thier spread them out over three days and don't do them both on the same day. If the barsd are simualr you ca n just study for one and hopefully have enough general info to answer the other, unfortunetly in my case half the WY bar is oil and gas law, so I gotta study that in addition to the normal stuff.
