fx forward/premium

Looking at the Schweser Quick Sheet the formula for a fwd premium/disc is as follows:

fwd prem/disc = (360/term in days)(fwd/spot - 1)

But just came a question in Schweser Qbank which just did a basic forward rate - spot rate = premium/discount

Is schweser bank wrong? is there a specific situation to use the formula in?

no worries figured it out, the formula in the quicksheet relates to the annualised premium not the actual premium/disc!!

thinking too much about the stupid little things!
