IIT Madras uses a structured credit system to quantify the academic workload for M.Tech courses. Each course is represented by a code in the format **L-T-E-P-O-C**. Here’s what each letter stands for:

- **L** : Number of Lecture hours per week
- **T** : Number of Tutorial hours per week
- **E** : Number of Extended tutorial hours per week
- **P** : Number of Practical (lab) hours per week
- **O** : Number of hours expected to be spent outside the class (self-study, assignments, projects, etc.)
- **C** : Total number of credits for the course

The sum of L, T, E, P, and O gives the total number of credits (C) for the course.

## Additional Details

- **Lecture (L)**, **Tutorial (T)**, **Extended Tutorial (E)**, and **Practical (P)** components reflect the contact hours per week.
- **O** (Outside class hours) captures the expected self-study or project work time.
- **C** (Credits) is the total, reflecting the overall academic load per week for the course.

## M.Tech Credit Requirements

- The minimum credit requirements for M.Tech programs are specific to each department and specialization.
- Credits are accumulated through core courses, electives, and project work, with typical total requirements ranging around 190 credits for the entire program, depending on the department.
