VITEEE 2027 Biology syllabus has not been released. The 2026 syllabus contains 10 units; these are the starting point for preparation, with their topics listed below.

Biology had 40 questions worth up to 160 marks in the 2026 paper. The marking was +4 for a correct answer and -1 for a wrong answer. Biology belongs to BPCEA and carries programme restrictions.

VITEEE Biology Topics: 2026 Syllabus

Unit	Topics
Taxonomy	Three domains of life; Linnaean, Whittaker, Bentham and Hooker classifications; non-chordates up to phyla and chordates up to classes; flowering-plant morphology/anatomy and cockroach structural organisation.

Biodiversity patterns, value and conservation; hotspots, endangered species, extinction, Red Data Book, botanical gardens, parks, sanctuaries, museums, biosphere reserves and Ramsar sites. Pollution control, solid/radioactive waste, climate change and mitigation; population growth, birth/death rates and age distribution.

Biology Questions and Marks

2026 paper detail	Value
Subject questions	40
Maximum subject marks	160
Share of 125 questions	32%
Full paper duration	150 minutes
Whole paper maximum	500 marks

The 32% share is calculated from 40/125. VIT does not assign a fixed question count to each chapter. Chapter-wise weightage must therefore be separated from the confirmed subject allocation.

The 150 minutes apply to the whole test, not to this subject alone. The paper pattern also includes the remaining science section, English and Aptitude.

Topics That Need a Separate Revision Slot

Area	Coverage
Classification scope	Non-chordates are specified up to phylum and chordates up to class; flowering plants and cockroach organisation also appear.
Molecular biology	DNA repair, RNA splicing and gene regulation are explicit, not just DNA structure.
Applied biotechnology	Keep the rice genome project, patents, biopiracy, single-cell protein and microbial applications.
Ecology and conservation	Ramsar sites, radioactive waste and population attributes are part of the list.

Use these entries to fill gaps in your notes, not as a prediction of which chapters will receive the most questions.

How to Practise Biology

Topic group	Practice task
Genetics	Solve Mendelian crosses and probability questions, then identify whether a ratio changes through linkage, incomplete dominance or codominance.
Cells and physiology	Redraw structures and label the location of each process. For a pathway, connect substrate, enzyme or hormone with its site and outcome.
Taxonomy and health	Compare organism groups and disease-pathogen/vector pairs. Separate the pathogen from the organism that transmits it.
Ecology and biotechnology	Practise applications: choosing an appropriate conservation method, reading a population curve or ordering recombinant-DNA steps.

Mendelian cross

In Aa × Aa, the genotype ratio is 1 AA : 2 Aa : 1 aa. If A is completely dominant, the phenotype ratio is 3 dominant : 1 recessive. The two ratios answer different questions.

This is an original worked example, not a past VITEEE question. The previous-year question-paper collection can be used for longer practice; keep the year and marking scheme of each paper separate.

Courses Available Through the Biology Route

The programme list below is the 2026 Biology-route admission list. It applied to PCB/PCMB candidates taking BPCEA and also to PCB candidates taking MPCEA. Taking the Mathematics paper did not give a PCB candidate unrestricted access to all BTech courses.

BTech programme	Campus
Biotechnology	Vellore, Chennai and VIT-AP
Computer Science and Engineering (Bioinformatics)	Vellore
Health Sciences and Technology	Vellore
Bioengineering	Bhopal
Computer Science and Engineering (Health Informatics)	Bhopal
Computer Science and Engineering (Education Technology)	Bhopal

The standard requirement was 60% aggregate in Biology, Physics and Chemistry, with at least 50% in Biology. For the all-programme PCM/PCMB route, it was 60% aggregate in Mathematics, Physics and Chemistry, with at least 50% in Mathematics. The specified SC/ST and regional relaxation reduced the aggregate requirement to 50%; VIT did not state a blanket waiver of the separate subject condition.

The regional relaxation covered Jammu and Kashmir, Ladakh, Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura. Community or nativity proof was required for the concession.

VITEEE Biology Syllabus 2027 FAQs

Biology Preparation

Is VITEEE Biology only Botany?+

No. Its ten units combine plant, animal, human, cellular, molecular and environmental biology. Human physiology and health are included alongside plant physiology and taxonomy.

Can I take Biology and get any CSE branch?+

No. The 2026 Biology route covered only specified programmes. Its CSE options included Bioinformatics at Vellore and Health Informatics and Education Technology at Bhopal, not unrestricted admission to every CSE specialisation.

Is the Biology section a separate entrance exam?+

No. BPCEA is a VITEEE paper route containing Biology, Physics, Chemistry, English and Aptitude. Biology replaces the Mathematics section; the other four subjects remain.

Does preparing Biology for NEET cover the whole VITEEE paper?+

It overlaps with much of the Biology syllabus, but VITEEE also has English and Aptitude. Its programme eligibility and marking rules must be handled separately, and the explicit VIT topic list remains the coverage checklist.

Should I wait for the 2027 syllabus before starting?+

You can begin with the published 2026 Biology topics. Treat that list as the preparation reference, not a confirmed 2027 notification. Keep the unit names in your notes so any later addition or deletion can be identified directly.

*The article might have information for the previous academic years, please refer the official website of the exam.
