L1 L2 questions at L3?

[sumz]

Just came across fixed income Qs where they asked to calculate duration. Nowhere in LOS they ask us to know that and nowhere in L3 text they did so.
I know its something basic. Should we brace ourselves for such quirks at L3?

Some basic stuff like this is possible; e.g., you should be able to calculate a holding period return.
