About This Set
These questions are a step up, closer to Tier 2: most need two steps or a careful setup, such as a chain of three sales, a markup followed by two discounts, or a false weight hidden behind a loss. Items marked [Tier 2] are mostly asked in Tier 2, so if Tier 1 is your only paper you can leave them for later. Allow about 35 minutes and finish the set before you check any answer. With 18 or more right, you can handle the longer profit and discount questions.
