Which IGCSE subjects are essential to get me into Economy or Engineering School?
Definitely Maths otherwise don’t even think of Economy or Engineering and Physics. If you want to do chemical engineering, I’d do chemistry as well. English lit and language should be compulsory too. Maybe a humanities subject – geography and a foreign language too. It’s A Levels that matter more than IGCSE subjects really. Education up to 16 years is important but not crucial. Just make sure you do well in the subjects above and pick good A Level subjects.
