The Chennai Mathematical Institute (CMI) is a specialised institute for higher education and research in mathematics, computer science and physics. Located in Siruseri, Chennai, it offers undergraduate programmes designed for students interested in mathematical reasoning, scientific problem-solving and research.
For students considering a degree that combines mathematics with computer science or physics, CMI offers four-year Bachelor of Science (Honours) programmes, with the option to pursue a minor in Data Science.
What can you study at CMI?
CMI offers three four-year undergraduate programmes for the 2027–28 academic session:
- B.S. (Hons.) in Mathematics
- B.S. (Hons.) in Mathematics and Computer Science
- B.S. (Hons.) in Mathematics and Physics
What is the structure of the BS (Honours) programme?
Students follow a common foundation in mathematics during the initial part of the programme. They subsequently choose a focus subject from mathematics, computer science or physics, depending on their interests and intended degree.
Students in all three programmes can also pursue a minor in Data Science, subject to completing the prescribed courses.
CMI provides a three-year exit option leading to a B.Sc. degree for students who complete the applicable academic requirements. Students who complete the full four-year programme receive the relevant BS (Honours) degree.
Who can apply to CMI?
Students who have passed or are completing their Class 12 or an equivalent qualification can consider applying to CMI’s BS (Honours) programmes.
CMI uses a common entrance examination for all three undergraduate programmes. Students do not select their specialisation when submitting their application. The choice is made after admission.
Since the programmes place considerable emphasis on mathematics, students should be comfortable with mathematical reasoning and problem-solving.
How does admission to CMI work?
Admission to the undergraduate programmes is primarily through CMI’s national entrance examination. The examination assesses mathematical aptitude through questions and problems based largely on material covered up to Class 12.
The examination includes two types of questions:
- Part A: Short-answer questions entered into a computer in a specified format. Assessment focuses on the correctness of the final answer.
- Part B: Longer mathematical problems requiring written solutions and justification of the reasoning used.
Applicants should consult CMI’s entrance examination syllabus and past papers for preparation.
Can you get admission to CMI without taking the entrance examination?
Yes. CMI provides an exemption from the BS entrance examination for students with exceptionally strong performances in the National Olympiads in Mathematics, Physics and Informatics. Specific Olympiad achievements and eligibility conditions apply.
The following categories are identified for direct admission under CMI’s Olympiad provisions:
- Mathematics: Students who qualified for the International Mathematical Olympiad Training Camp (IMOTC) or the European Girls Mathematical Olympiad Training Camp (EGMOTC) in Class 11 or Class 12.
- Physics: Students who qualified for the Orientation Cum Selection Camp (OCSC) in Physics in Class 11 or Class 12.
- Informatics: Students who qualified for the International Olympiad in Informatics Training Camp (IOITC), were shortlisted for team selection for the European Girls Olympiad in Informatics (EGOI), or received a gold or silver medal at the Indian National Olympiad in Informatics (INOI) in Class 11 or Class 12.
Students who meet these criteria should review the current admissions instructions to confirm the applicable route and documentation requirements.
