Students join the polytechnic, after completing their course of study in secondary education. For further study in engineering they should have more knowledge about science. Only then, they can apply the principles of science in their branch. Therefore motivation of students is the main responsibility of the teachers of science.

Mathematics is the mother of all sciences. Some of the subjects in Engineering deal with mathematical derivations, based on calculus. Hence the students are taught the fundamentals in differential and integral calculus, which will be of great help to them later on.

English has truly become very much relevant and important for the students of polytechnics. Learning English for everyday communication is among the basic needs of a technical professional in this era of globalization. Therefore, guidance and motivation of students are the main responsibilities the teachers of this subject.
