Duration and Eligibility
Course Duration
The most common undergraduate programs in CSE are Bachelor of Technology (B.Tech) and Bachelor of Engineering (B.E.). These typically span a duration of four years, divided into eight semesters. Each semester combines theoretical subjects, lab components, and project work. Students progressively advance from basic science and engineering courses to advanced computer science subjects and specializations.
Eligibility Criteria
To be eligible for enrollment in a CSE undergraduate program, candidates must meet the following criteria:
- Completion of 10+2 or equivalent examination with Physics, Chemistry, and Mathematics (PCM) as core subjects
- Minimum aggregate marks as stipulated by the university or college (generally between 50% to 60%)
- Qualifying scores in entrance examinations such as:
- JEE Main / JEE Advanced
- State-level engineering exams
- Private university entrance tests (e.g., VITEEE, SRMJEEE)
