My school offers the EXACT same courses - I wonder if we go to the same one lol I could give even more specific recommendations. Anyways geo HL is generally an easy 6/7, 5 at the VERY minimum. I would recommend taking bio if you’re someone who likes or is good at memorization. From the opinions of lots of my classmates physics HL is VERY hard and tbh I would say it’s unnecessary if you’re doing Econ. Don’t think I would recommend art at all, I would use it to add on geo as an extra humanities course. Cant speak to math bc idk what the requirements are for Econ but I’d look into the requirements for different unis you’re interested in going to. Feel free to PM me!
