B.Sc Chemistry Entrance Exams 2026: CUET, IAT, NEST, Pattern & Eligibility

Most B.Sc Chemistry entrance exams in 2026 are led by CUET UG, the single national test used by Delhi University, BHU, Jamia Millia Islamia and dozens of central, state, private and deemed universities to admit students into B.Sc and B.Sc (Hons.) Chemistry. A smaller set of research institutes (IISERs, NISER) run their own aptitude tests for integrated BS and BS-MS chemistry programmes, while several state and private universities still admit through their own entrance exams or Class 12 merit. This page lists every major B.Sc Chemistry entrance exam for 2026, its pattern, eligibility and how the chemistry section is scored.

Which entrance exams are required for B.Sc Chemistry admission in 2026?

There is no single compulsory exam for all colleges. Admission to B.Sc Chemistry in 2026 happens through three main routes: (1) CUET UG for most central and many state/private universities, (2) institute-specific aptitude tests such as IISER IAT and NEST for research-oriented integrated programmes, and (3) Class 12 merit or university-level entrance tests at many state and private colleges. Always confirm the route on the individual college’s admission page.

Route and participating institutes change each cycle; verify on the official admission portal before applying.

CUET UG 2026: the main B.Sc Chemistry entrance exam

CUET UG is the primary entrance exam for B.Sc Chemistry in 2026, conducted by the NTA as a computer-based test. To be considered for B.Sc (Hons.) Chemistry, candidates typically appear in the Chemistry domain paper along with Physics and Mathematics/Biology, plus one language, and merit is prepared from these CUET scores. Delhi University, for example, requires Chemistry with Physics and Mathematics/Applied Mathematics in CUET for its B.Sc (Hons.) Chemistry admission.

CUET UG 2026 exam pattern (per domain subject)

NTA revises the exam pattern periodically; the number of questions to attempt and marks have changed across cycles, so always cross-check the current CUET UG information bulletin.

CUET UG 2026 eligibility for B.Sc Chemistry

Candidates must have passed or be appearing in Class 12 (10+2) from a recognised board. For B.Sc (Hons.) Chemistry, the required Class 12 subjects usually include Chemistry along with Physics and Mathematics (some universities accept Biology). Minimum aggregate typically ranges from 50% to 60% depending on the university and category, though the final merit is driven by CUET scores.

IISER Aptitude Test (IAT) 2026 for BS / BS-MS chemistry

The IISER Aptitude Test (IAT) is the entrance exam for chemistry at the Indian Institutes of Science Education and Research. IAT 2026 admits students to the 5-Year BS-MS dual degree (offered across IISERs) and the 4-Year BS programme (at IISER Bhopal and IISER Tirupati), where chemistry is one of the major disciplines. It is a single computer-based paper covering Biology, Chemistry, Mathematics and Physics.

Eligibility: candidates should have completed Class 12 in the science stream in 2024, 2025 or 2026, with at least three subjects among Biology, Chemistry, Mathematics and Physics. Applicants appearing in the 2026 board exam are eligible provided they qualify before counselling.

NEST 2026 and other research-institute exams

NEST (National Entrance Screening Test) is used for integrated M.Sc programmes at NISER Bhubaneswar and UM-DAE Centre for Excellence in Basic Sciences (CEBS), Mumbai, where chemistry is among the offered majors. Like IAT, it is aimed at students who want a research career in the basic sciences rather than a standalone three-year B.Sc. These integrated routes are strong alternatives for chemistry aspirants who plan to pursue a master’s and research.

State and university-level entrance tests

Several state and private universities admit to B.Sc Chemistry through their own entrance exams or Class 12 merit rather than CUET. Many autonomous and private colleges continue to shortlist candidates directly on 10+2 marks, while some state universities run a state common entrance test. Because participation in CUET and cut-offs vary widely, it is best to shortlist target colleges first and then confirm each one’s exact admission route.

How to prepare for B.Sc Chemistry entrance exams 2026

The single most effective preparation strategy is to master the Class 11 and 12 NCERT Chemistry syllabus, since CUET, IAT and NEST all draw heavily from it. Focus on Physical, Organic and Inorganic Chemistry fundamentals, practise MCQs under timed conditions (each domain paper runs 60 minutes), and be mindful of negative marking. Aligning your revision with the standard undergraduate topics also helps — see the detailed B.Sc Chemistry syllabus for the topics that carry through from entrance to degree.

Important dates and where to apply (2026)

Key windows in 2026: CUET UG chemistry papers were held across May 2026, IAT 2026 registration and exam were completed with results and counselling underway, and university allocation lists (for example, Delhi University’s first allocation) began in July 2026. Exact application, exam and counselling dates differ by exam and university, so track the official portals — cuet.nta.nic.in for CUET UG and iiseradmission.in for IAT — and each university’s admission page for authoritative dates.
