Physics, Chemistry, and Engineering are difficult if you expect to take the easy way and sail through. Math is essential for all of them.
I'm good at Math and I passed Chemistry.
Because the majority of economics, physics and engineering and general chemistry requires you to be able to calculate, not just learning concepts.
Sounds backwards to me.
Not necessarily but you will be expected to understand computing - as a tool for aiding complex calculations, not an end in itself. You are right about the maths, but economics? Engineering is the practical application of science, principally physics but also chemistry.
Apparently, you haven't had much exposure to Physics, Chemistry, or Engineering, have you. Yes, they all do. In increasing order of mathematical intensity, they are Chemistry Engineering Physics
For Physics and Engineering yes, but not so much for Chemistry.
No. It is an absurd falsehood, to which no credence should be paid.
Engineering(except software and electrical) Accounting Economics Mathematics Physics Chemistry
Engineering is Applied Physics , Economics (affordability) and Art (think Apple).
i think chemistry is more difficult then physics or biology.
