yes ... just study
You'll certainly not have difficulty in physics and engineering BECAUSE you are good at math or economics; math, especially, is important in physics.
Not so sure about economics but you will need physics.
No
Of course, there isn't a reason not to, because mathematics is the language of economics, science and engineering(with the exception of computer programming).
Accounting, Business and Engineering
Yes.
I'm good at Math and I passed Chemistry.
Sounds backwards to me.
Engineering(except software and electrical) Accounting Economics Mathematics Physics Chemistry
It is very possible you would do well. Check out some engineering colleges and ask a few questions
It's absurd to draw such a general correlation.
Because the majority of economics, physics and engineering and general chemistry requires you to be able to calculate, not just learning concepts.
