This had been bugging me all weekend...I took a Wiley practice exam and one of the simulations had me complete an Excel-type spreadsheet with formulas to re-calculate depreciation. The instructions stated that depreciation was straight line based on a percentage and that a half-year of depreciation should be calculated for any asset retirements or purchases. So for example, I typed in this formula to calculate depreciation on a purchased asset...

(B5*C5)/2 where B5 = book value and C5 = provided % rate

After checking my answers, Wiley marked each of my formulas wrong saying that the correct formula should be...

0.50*B5*C5

Obviously both formulas arrive at the same amount, but Wiley marked my answers wrong!! Is this something I need to worry about on the actual exam? Or is it just a Wiley glitch? Anyone have any thoughts?
