CBSE Class 12 Biology (subject code 044) has a 3-hour, 70-mark board theory paper and 30 marks of practical assessment, built closely on the NCERT textbook. Our CBSE Class 12 Biology course follows the latest NCERT syllabus chapter by chapter: sexual reproduction in flowering plants, human reproduction, reproductive health, principles of inheritance and variation, molecular basis of inheritance, evolution, human health and disease, microbes in human welfare, biotechnology and its applications, organisms and populations, ecosystems and biodiversity. Each lesson is live and one-to-one with a verified subject teacher, who explains concepts from first principles, solves NCERT and exemplar questions with you, and practises board-pattern questions, sample papers and previous years' questions. It also covers the NCERT lines that NEET questions are built on. Suitable for students in India and at CBSE schools in the Gulf and abroad, with lesson times in IST and GST.

Course structure
In short: this course gives one-to-one online tutoring for CBSE Class 12 Biology. A verified tutor explains every chapter, works through textbook exercises and sample-paper questions step by step, and builds the exam technique you need for the board exam.
CBSE Class 12 Biology is the senior secondary biology subject of India's Central Board of Secondary Education, covering reproduction, genetics and evolution, biology and human welfare, biotechnology and ecology. It is assessed by a CBSE board theory exam and a school-based practical exam, and is the core of NEET biology.
This course covers every NCERT chapter one to one with a verified biology tutor.
For wider support, see our biology tutoring page, or revisit the foundations in the CBSE Class 11 Biology course.
CBSE Class 12 Biology follows the CBSE syllabus. Class 12 ends with the board examination, set by CBSE, alongside internal or practical assessment where the subject includes it. Marks, durations and question types can change from year to year, so check the current CBSE curriculum for your exam year. Tutors follow the textbook chapters your school teaches and practise the question styles in recent sample papers.
| Unit | Chapters |
|---|---|
| Reproduction | Sexual reproduction in flowering plants; human reproduction; reproductive health |
| Genetics and evolution | Principles of inheritance and variation; molecular basis of inheritance; evolution |
| Biology and human welfare | Human health and disease; microbes in human welfare |
| Biotechnology and its applications | Biotechnology: principles and processes; biotechnology and its applications |
| Ecology and environment | Organisms and populations; ecosystem; biodiversity and its conservation |
Here is a typical genetics question: cross two pea plants heterozygous for tallness (Tt × Tt).
| T | t | |
|---|---|---|
| T | TT | Tt |
| t | Tt | tt |
Genotype ratio 1 TT : 2 Tt : 1 tt; phenotype ratio 3 tall : 1 dwarf.
Students most often lose marks through the habits below. Each is easy to fix with regular practice and feedback.
| Mark-loser | What to do instead |
|---|---|
| Diagrams unlabelled | Draw neat, fully labelled diagrams |
| Vague terminology | Use NCERT terms exactly |
| Processes out of order | Learn the sequence of each process |
| Genetics ratios wrong | Draw Punnett squares carefully |
| Long answers unstructured | Use points and subheadings |
CBSE board questions are based closely on the NCERT textbooks, so tutors work through NCERT text, in-text questions and exercises first, then CBSE sample question papers and previous years' papers. Recent papers include more competency-based questions, such as case-based and assertion-reason questions, and tutors practise these question types specifically. The Class 12 exam is the CBSE board exam, usually held in February and March.
Lessons are live and one to one on video with a shared whiteboard, at times that suit students in India and abroad. Your tutor follows the latest CBSE syllabus and your school's schedule. See also CBSE Class 11 Biology, ISC Class 12 Biology and our Biology subject page.
The CBSE Class 12 Biology syllabus covers reproduction, genetics, biotechnology and ecology, and this course teaches each NCERT chapter in live 1-to-1 lessons with diagrams and sample papers.
This course suits Class 12 CBSE students in India and in CBSE schools abroad, including the Gulf.
Prerequisites: CBSE Class 11 Biology, including cell biology and human physiology.
Course length: 45 lessons across 12 chapters.
| Stage | Topics | What you can do afterwards |
|---|---|---|
| 1 | Reproduction in plants and humans; reproductive health | Draw diagrams and explain reproductive processes |
| 2 | Inheritance and variation; molecular basis of inheritance; evolution | Solve genetics problems and explain DNA |
| 3 | Human health and disease; microbes; biotechnology | Explain disease, immunity and biotechnology |
| 4 | Organisms and populations; ecosystems; biodiversity | Explain ecological relationships |
