Correct me if im wrong but I though for IB you needed to take English, an MFL, a humanity, a science, maths and an extra subject?
Disregarding that though:
You higher choices across both (the same obviously) are good for engineering, especially maths and physics.
For SL economics is a solid choice, not really relevant to engineering directly but if you’re interested and will do well then it’s a great option i would say. Then geography and English vs biology and chemistry I would say for engineering chemistry is a good idea as some engineering routes will want chemistry so if you think you’ll enjoy it, can get a good grade and are interested in chemical engineering then I would say definitely go with it. Other than that for SL pretty much take what you want and what you think you’ll enjoy and excel at! So in conclusion: HL maths, physics and dt is excellent for engineering, chem for SL is a solid choice, other than that take what you think you’ll enjoy and do well at. Maybe check the diploma for your school because your programmes looking quite irregular for the IB.
Hope this helps, have a great day!
