GCE A level Economics - exam board Edexcel. Economics is an interesting and challenging subject, where students learn about Microeconomics and Macroeconomics. Micro being related to how markets work and how businesses behave and Macro being related to the UK economy as well as global economic issues such as poverty and inequality. It would be beneficial, although not essential, for students to have studied business at GCSE prior to choosing this subject at A Level as this will give them a foundation to build upon. Numeracy is also a vital skill required to perform well in Economics and a strong grade in GCSE Maths is a pre-requisite to study on this course. Several topics in this course are also touched upon in the A Level business course. Many students in the past have found it beneficial to study the two subjects alongside each other as they are complementary, however, it is important to consider university entry requirements, or if you have a specific career pathway in mind as some establishments prefer a wider spread of subjects to be studied.
