Are these all full year classes? 10 classes seems like a lot otherwise on top of extra curriculars and perhaps a bit of free time for hobbies, family time etc. I guess if your gpa is low I don’t see how taking more classes and spreading yourself thinner will help vs focusing more on fewer classes.
Since your not good at math (evident by geometry in 11th grade) you may be better off taking fewer classes and spending more time on help. However some people struggle with algebra and find geometry easy to hopefully that is you. I would see if you can find out the math level and amount for economics but if you struggle with math I would pass on it. Whatever grade you get in dual enrollment classes will not only be seen when applying to undergrad but also for grad school down the road. You might want to talk to your school about an honors science that may involve less math - don’t take an AP class just because it is an AP class.
