B.Sc. Physics is an undergraduate science degree focused on understanding matter, energy, motion, fields and physical laws through theory, mathematics and experimentation. In India, CUET-UG 2026 is a major common gateway for participating universities, while other institutions use merit or university-specific admission routes; the degree commonly leads toward M.Sc. Physics, research and technical careers.

Quick Overview

Introduction

A B.Sc. Physics is an undergraduate science degree that builds a systematic foundation in mechanics, electricity and magnetism, thermal physics, optics, modern physics, electronics and mathematical methods, typically combining classroom theory with laboratory work. It develops quantitative reasoning, experimental skills, scientific modelling and problem-solving that can be applied across research, technology and data-oriented fields. Practical laboratory work is an important part of the academic experience, alongside mathematical treatment of physical systems. In India, admission is not controlled by one single national process: CUET-UG 2026 is a major common gateway for participating universities, while other universities use merit or their own entrance processes. The degree commonly supports progression to M.Sc. Physics, research, technical and analytical roles, with teaching careers requiring the relevant higher qualification.

Duration & Structure

Under the UGC/NEP 2020 framework, undergraduate programmes can follow a 3-year or 4-year structure with multiple entry and exit points; a three-year pathway leads to a Bachelor\\\\\\\'s degree, while a four-year pathway can lead to a research-oriented Bachelor\\\\\\\'s degree. The framework can also provide an undergraduate certificate after 1 year and a diploma after 2 years, subject to the prescribed credit requirements. The exact implementation is university-specific: for example, the University of Delhi\\\\\\\'s Physics curriculum is structured across 6 or 8 semesters over 3 or 4 academic years, with theory and practical components.

Eligibility Criteria

The standard academic gateway is Class 12/equivalent with a science background and Physics; Mathematics is a programme-specific requirement at many universities, including the Physics routes at BHU and Delhi University. For CUET-UG 2026, NTA accepts recognized 10+2/equivalent qualifications, including recognized board, university or equivalent international qualifications, and states that there is no age limit to appear for CUET, although a university can prescribe its own age rule.

• Academic Baseline: 10+2/equivalent; Physics is essential, and Physics + Mathematics is a common requirement for B.Sc. (Hons.) Physics.

• Minimum Marks: There is no single India-wide cutoff. Current 2026 examples include 50% for General and 45% for SC/ST at participating institutions; OBC/EWS/PwD rules are institution-specific, so verify the target university\\\\\\\'s bulletin. 

• Age / Other Prerequisites: CUET-UG 2026 has no age limit, but the admitting university may set an age condition; subject-wise CUET combinations must also match the programme requirements.

Entrance Exam & Entry Routes

• National-Level: CUET-UG → iSathi CUET-UG Details

• National-Level: JEE Advanced → iSathi JEE Advanced Details — applicable to selected 4-year B.S. Physics programmes such as IIT Kanpur. 

• State-Level: No single state-wide B.Sc. Physics entrance exam operates across India; state/public universities commonly use merit or their own university-level entrance process.

• Direct Entry: Merit-based admission using Class 12 performance is available at institutions that do not mandate an entrance examination.

• Lateral Entry: Not applicable to the standard B.Sc. Physics pathway.
