hi,

see applied mathematics is the main subject to learn about the modern computing Technics, data science, statistical modelling and artificial intelligence and machine learning. it is predicted by most of the tech giants companies like infosys, IBM , microsoft, tcs that in next six years the AI AND data science related field have wide demand. so There is decent scope to study mathematics and computing engineering. however engineering is a subject where you learn many things out of the syllabus of any university level exam. cause in class room you may be taught about the theoretical part, but you have to make your self established to crack and excel the technical knowledge. so besides the university syllabus many of the extra programming, curricular activities need to complete.

hope you may understand.
