M.Tech. in Renewable Energy Engineering 

at Kelappaji College of Agricultural Engineering and Technology, Malappuram

Below are some of the general subjects that you can pick during your BTech studies, as these course will advance your technical and practical knowledge:

Mathematics: A mathematical background includes understanding of Calculus, Linear Algebra, Differential Equations and Statistic Stamina.
Physics: Mechanics, electricity & magnetism, kinetics & dynamics, thermodynamics and wave & optics.
Chemistry: This common general chemistry course involves sub-topics such as organic chemistry, inorganic chemistry among others.
Programming: C+,  Python,  Java
Engineering fundamentals: Statistics, dynamics, fluids and their action, heat and its work, properties of matter
Engineering design: Aesthetics, reasoning process, design tools and methods, using of computer-aided design (CAD).

Rest, the subjects taught in the BTech courses would be specialization-specific, based on your chosen field.

The BTech syllabus is not similar in all the Indian colleges. Talking about the first year of BTech, the general subjects taught are almost similar that include Physics, Mathematics, Chemistry and other engineering fundamentals to provide a basic foundation for the BTech course ahead. Further, the BTech syllabus will differ on the basis of the specialisation you have chosen and the college, different colleges follow their own set of guidelines regarding the course curriculum that includes both core and elective subjects along with practical lab work.
