4 test grades 93, 86, 92, 80

5 test average 94

what are steps?

Since your problem is incomplete, I don't know what you're looking for. However, if you need to know the number of points needed to bring a grade up to 94 --

4-test average = 93 + 86 + 92 + 80 = 351

351/4 = 87.75 = 88

5* 94 = 470

470 - 351 = 119
