Sad to tell you geclaw, the most common review course NC students use is still
BarBri (
MicroMash is still owned by
BarBri)
If you have already passed the Ohio one, tho, most likely you know what's going on and may be able to pass simply by focusing on the MBE portion (like you already are) and get used
BarBri materials/outlines and practice the essay portion on your own.
BarBri is not bad for home study, but it is quite expensive and may be unnecessary for someone who has already passed one bar like you:)
