CUET UG 2026 Science:Selecting subjects for CUET UG 2026 demands a well-planned strategy that balances your Class 12 academic background with university-specific admission rules. While the National Testing Agency (NTA) provides a broad list of 23 domain subjects, whether a subject is considered “mandatory” is strictly decided by the eligibility conditions of the chosen university and the specific programme applied for, such as B.Sc. Honours or B.Sc. Programme.
The Subject Mapping Rule, originally introduced by Delhi University (DU), continues to remain a decisive criterion for CUET UG 2026 admissions. As per this rule, candidates are allowed to appear only for those CUET subjects that they have studied and passed in their Class 12 board examinations. Attempting a subject like Computer Science in CUET without having studied it in Class 12 can lead to rejection of merit scores by top central universities.
Core science subjects include Mathematics, Physics, Chemistry, Biology, Language, and the General Test. Aspirants can now go through subject-wise key concepts for CUET Science preparation. The CUET Science 2026 exams will be held between May 11 and May 31. The CUET is a mandatory national-level entrance test for students from science, commerce, and arts streams seeking admission to central, state, private, and deemed universities across India.
List Of CUET UG Subjects Are Mandatory for Science Aspirants
For science candidates appearing in CUET UG 2026, subject selection will be governed by two fundamental principles: Subject Mapping (choosing subjects studied in Class 12) and Programme-Specific Eligibility (selecting subjects required for the target degree). Although the NTA permits candidates to choose up to five subjects, selections must be made carefully to maximise eligibility across major central universities such as DU, BHU, and JNU.
Mandatory CUET UG Subject Combination for Science Aspirants (Table Unchanged)
| Stream / Group | Mandatory Section I (Language) | Mandatory Section II (Domain Subjects) | Mandatory Section III (General Test) |
|---|---|---|---|
| PCM Group (Physics, Chem, Math) | Any One Language (English/Hindi highly recommended) | Physics + Chemistry + Mathematics | Required only for specific B.Tech or B.Voc programs. |
| PCB Group (Physics, Chem, Bio) | Any One Language (Required for eligibility in most CUs) | Physics + Chemistry + Biology (Biotech/Biochemistry also accepted) | Required for B.Sc. Agriculture or Paramedical at some universities. |
| Agriculture Group | Any One Language (Qualifying only) | Agriculture + Biology + Chemistry (or PCM/PCB combination) | Highly recommended for all-India university eligibility. |
| Computer Science / IT | Any One Language | Mathematics + Physics + (CS / IP / Chemistry) | Often mandatory for JNU or specialized DU IT programs. |
How to Choose CUET 2026 Science Subjects?
The National Testing Agency (NTA) has streamlined the subject selection process for science students by limiting the total number of selectable subjects to five. Choosing the right subject combination is one of the most critical steps, as it directly impacts eligibility for reputed institutions such as DU, BHU, and JNU.
