The grade you need to pass the program is set by the school, not the state. Lansing Community College requires 81% or higher, where another competing program requires only a 71%.
As for the test, Michigan uses the National Registry for their testing.
Check the program documents that were given to you at the beginning of your program. They should tell you what you need to know. The program that I went through (not LCC) you had to have an 80%+ to even sit for the final.
