g = rnorm(n=130, m=82, sd=10)
g[g>100] = 100
g[g<1] = 1
B = boxplot(g)
divs = c(min(g), B$stats[1:4] + diff(B$stats)/2, max(g) )
### to run interactively, remove the divs
### D1 = do.grades(g, tit="GEOL 105 Exam 1")
### otherwise use previously calculated divs:
D1 = do.grades(g, divs=divs, tit="GEOL 105 Exam 1")
checkgrades(D1 )
