Assessment Criteria Connection

Real Student Mistakes

Example 1

Why it lost marks: This statement is incomplete and doesn't consider the role of monetary and fiscal policies in influencing exchange rates. Correct approach: Understand that exchange rates are influenced by a combination of factors, including supply and demand, monetary and fiscal policies.
