Hi dear,

Hope you are doing well!

Now let's go through your question.

Basically, Chemical engineers use chemical formulas and discoveries made in laboratories and apply them to much larger scale for commercial use.

They are often tasked to accomplish this with safety, cost-efficiency and profit in mind. While entry-level positions require only a bachelor's degree in chemical engineering, advanced training options including certificate programs are available and can increase hiring and income potential.

It is necessary to have maths as a common subject in 12th from a recognized Board to pursue engineering in chemical in India.

Thank You & All the best!

Hey,
Being an engineering discipline one cannot get away from mathematics.Chemical Engineering deals with very complex situations (may it be Heat transfer, Mass Transfer, Fluid flow operations, Chemical ReactionEngineering etc.) Numerical methods, partial differential equations,  integrations  forms an integral part of the solution.  So, yes Chemical Engineering requires you to knowMathematics.

Hope this helps.
