IIT Delhi offers undergraduate (UG) and postgraduate (PG) level courses in Semester I (nominally July-Dec) and Semester II (nominally January-May) every year. There is also a summer semester, when very few courses are on offer. Most faculty members teach only during Semesters I and II. The list of all courses is available in the courses of study Each academic unit offers a selection of these each semester and designates the instructor(s) for each. The teaching load and faculty strength of a unit can vary from unit to unit and semester to semester. Its faculty is expected to share the teaching load. Most new faculty members require some bootstrap time in the beginning, and the heads of units take this into account when assigning courses to a new faculty member. Please talk to your Head about your expected load in the first few semesters.
Course credit system
Each course at IIT Delhi offers a certain number of credits and may have lecture, tutorial and practical components, its L-T-P structure. Hence, a 3-1-2 course has three hours of instruction as lectures, one tutorial hour, and two hours of practicals per week in a 14-week semester. A student passing this course would earn 5 credits (an hour of practical work offers half a credit; other hours offer a full credit). Tutorials are usually held in small groups (compared to lectures) and focus on problem solving exercises (rather than introduce new material like lectures do). IIT Delhi also offers some non-credit courses, a few of which all students are required to take. These still form a part of the teaching load and work somewhat like lectures. The contents of these courses are not disciplinary, and their modes can vary. If you are asked to teach a part of such courses, please seek assistance from the head and others with experience teaching them.
Some faculty members may be responsible for all components of a course, while others may be responsible only for, say, the tutorial or practical components. Courses in which multiple faculty members are involved in instruction have a designated course coordinator. The coordinator maintains a uniform policy, manages exams and grading, and manages the administration of the course. Many courses also have PG students (and some exceptional UG students in some cases) assigned as teaching assistants. TAs for a course are assigned mainly by the academic unit (Head) that offers that course. These TAs can help with the administration. TAs do not teach and may only have a limited role in grading under supervision. As examples, TAs can help invigilate, mark objective-type questions, tabulate marks, assist with practicals, etc. TAs can also be good conduits to students, particularly ones that are less comfortable approaching the instructor. It is also useful to seek help from STIC (student teacher interaction council), which even supports informal outings of faculty with students.

Courses can be core for a program (meaning all students in that program are required to pass that course) or elective (meaning the students elect to take that course). Each course is identified by a label, aka its course number, that indicates the academic unit that offers it and the level of the course.
