A math problem

If you want to calculate your score from the April 13th practice test (not the May 1st test), use the following formula:

X = (#correct on MC Section) x 1.2272 (DO NOT round)

Y1 = (score on Q1) x 3.0556 (DO NOT round)

Y2 = (score on Q2) x 3.0556 (DO NOT round)

Y3 = (score on Q3) x 3.0556 (DO NOT round)

Z = X+Y1+Y2+Y3 (Round to the nearest whole number)

If Z is between 115-150, you'd earn a 5.
If Z is between 100-114, you'd earn a 4.
If Z is between 82-99, you'd earn a 3.
If Z is between 55-81, you'd earn a 2.
If Z is between 0-57, you'd earn a 1.
