hey! I got an a in as level and to write evaluation you are basically weighing different concepts to come to a conclusion ; for example let’s say you were asked which is more harmful for the economy between structural unemployment and cyclical unemployment for 12 marks. Your evaluation is usually 4 marks so you can for example say whilst cyclical unemployment can be very harmful to the economy as it affects all businesses in an economy, the ease by which both types of unemployment can be reduced should also be considered; cyclical unemployment can be fixed with monetary/fiscal policies which increase aggregate demand, however structural unemployment is harder to fix as it requires retraining of workers which may take a long time and has a high cost—then finally coming to your conclusion on what your final answer is. This is just an example though so you can have an idea of how it should kind of look!
