IIT Kanpur offers a variety of Elementary Science Options( ESO ) courses to choose from to nurture science interest in students apart from core departmental and compulsory courses. As the name suggests, all of these courses (9-10) are there to lay the foundation stones for understanding the respective domains like thermodynamics, data structures, fluid mechanics etc. Every UG deparment has laid down some minimum credit requirements that are to be fulfilled by choosing 3-4 courses of your like to gain a substantial understanding in respective areas.
