I've done 4 so far and halfway thorugh my 5th. I'm aiming for 6 altogether from now til the exam.
Good job!
Doing tons of practice exams isn't essential for Economics (I did 0 after all).
What's important is practicing MC and your approach to the 6-8 mark questions.
Is there a specific structure you should adopt when answering those questions? And how long should you spend on them?
My teacher suggests spending no more than 8 minutes for an 8 mark question. For 6 marks, a bit less.
When a questions asks about the "current" context (for example, the current policy mix), is it referring to the past 4 years or just the past year?
The budget is reviewed every year, with the monetary policy being considered every month. Therefore, when they refer to the 'current' relationship between the two, I'd think that they're talking about the past year. Questions relating to a 4-year period are usually relating to trends shown on a graph or providing and explaining a policy implemented recently.
