Computer Science Engineering (CSE) offers opportunities in software engineering, artificial intelligence (AI), machine learning (ML), data science, quantitative engineering, mobile application development and cybersecurity. However, the journey towards these careers can begin long before college.
For students in Classes 9–12, understanding JEE Main, JEE Advanced, eligibility requirements and engineering entrance preparation is an important first step towards building a successful technology career.
1. What Is JEE Main and Which Institutions Accept It?
JEE Main is a national-level entrance examination conducted by the National Testing Agency (NTA). Its B.E./B.Tech paper is used for admission to undergraduate engineering programmes at participating National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), and other Government Funded Technical Institutes (GFTIs).
JEE Main also serves as the qualifying examination for students seeking eligibility to appear for JEE Advanced, subject to the applicable rules.
Examples of institutions and categories include:
- NITs: NIT Tiruchirappalli, NIT Surathkal and NIT Rourkela.
- IIITs: IIIT Allahabad and other participating IIITs.
- Other institutions: IIEST Shibpur and participating GFTIs.
JEE Main also has separate papers for B.Arch. and B.Planning. Their admission pathways differ from the B.E./B.Tech paper.
2. What Is JEE Advanced and Which Institutions Accept It?
JEE Advanced is the entrance examination used for admission to undergraduate programmes at the Indian Institutes of Technology (IITs). Only candidates who meet its eligibility requirements can appear, including the requirement to qualify through JEE Main for Indian candidates under the standard route.
For 2026, JEE Advanced shortlists candidates from among the top 2,50,000 successful candidates in the JEE Main B.E./B.Tech paper, subject to the official category-wise rules and tie provisions.
Examples of IITs include IIT Bombay, IIT Delhi, IIT Madras, IIT Kanpur, IIT Kharagpur, IIT Guwahati and IIT Roorkee.
IISc Bengaluru also offers certain undergraduate programmes through specified admission routes; its B.Tech programmes for 2026–27 use JEE Advanced ranks through JoSAA.
Important: Qualifying an entrance examination does not guarantee admission. Final admission depends on rank, seat availability, category, programme preferences and the applicable eligibility rules.
