ISI Admission Test: B.Stat & B.Math Guide (Indian Statistical Institute)

The ISI route into pure statistics and mathematics

The Indian Statistical Institute (ISI) is a specialised institution of national standing for statistics, mathematics and allied quantitative sciences. Its two flagship undergraduate degrees are the B.Stat (Hons.) and the B.Math (Hons.) — rigorous, research-oriented programmes for students who want a deep grounding in pure mathematics and statistics rather than a general science or engineering path.

The B.Stat (Hons.) is offered at ISI Kolkata, and the B.Math (Hons.) is offered at ISI Bengaluru. Both are demanding programmes that select through ISI's own admission test — they are not filled through JEE, CUET or any other common exam. This makes ISI a distinctive, uncrowded route for genuinely mathematics-inclined students.

The degrees and what they lead to

Both B.Stat and B.Math are honours degrees with a strong theoretical core. The curriculum builds analysis, algebra, probability and (for B.Stat) statistical theory to a level well beyond a typical bachelor's, preparing students for advanced study and research.

Graduates commonly progress to ISI's own master's programmes (such as M.Stat or M.Math) or to postgraduate study and research elsewhere in mathematics, statistics, data science, economics and related quantitative fields. The exact curriculum and duration are set by ISI — confirm them on the official programme pages before applying.

• B.Stat (Hons.) — offered at ISI Kolkata
• B.Math (Hons.) — offered at ISI Bengaluru
• Theory-heavy: analysis, algebra, probability, statistics
• Natural feeders into M.Stat / M.Math and quantitative research

Who is eligible

Eligibility is straightforward but specific: candidates must have completed (or be appearing in) 10+2 Higher Secondary education, or an equivalent, with Mathematics and English as subjects.

Because the programmes are mathematics-intensive, a strong command of school mathematics is essential rather than merely a pass. The precise qualifying-year rules and any category relaxations for a given cycle are published in the official ISI prospectus — verify them there.

• 10+2 (or equivalent) with Mathematics and English
• Suited to students with strong, concept-level mathematics
• Confirm qualifying years and any relaxations in the official prospectus

Selection: objective paper, subjective paper and interview

Admission is through a written test followed by an interview. For the undergraduate programmes, the written admission test has two parts held on the same day: an objective (multiple-choice) paper, often referred to as the Undergraduate Aptitude Test, and a subjective paper requiring full mathematical solutions.

A key rule shapes preparation: the subjective paper is evaluated only if you clear the objective paper. Candidates who qualify on the written test are then called for an interview conducted by the institute. Final selection reflects performance across these stages.

The subjective paper is what makes ISI distinctive — it rewards clear, rigorous mathematical reasoning and proof-writing, not just quick multiple-choice answers. The exact number of questions, timing and marking for each part are given in the official prospectus and syllabus documents.

• Written test in two parts on the same day: objective + subjective
• Subjective paper evaluated ONLY if the objective paper is cleared
• Shortlisted candidates are called for an interview
• Verify exact question counts, timing and marking in the official prospectus

Stipend, applying and preparing

A notable feature of the B.Stat and B.Math programmes is that selected students typically receive a monthly stipend during the course, subject to satisfactory academic performance — one reason these programmes are attractive to committed mathematics students. Confirm the current stipend amount and conditions in the official prospectus.

Applications are made online through the ISI admission portal, where you register, complete the form and upload documents within the announced window. For preparation, the official syllabus and sample/past question papers on the admission portal are the definitive reference; the emphasis is on depth in school-level mathematics and the ability to construct complete solutions. No coaching can guarantee selection — the outcome depends on your performance across the test and interview.

• Selected students typically receive a monthly stipend (verify the amount)
• Apply online at the official ISI admission portal
• Prepare from the official syllabus + past/sample papers
• Practise full written solutions, not only multiple-choice
