ISC Class 12 Biology (863) has a 3-hour theory paper worth 70 marks and a practical component worth 30 marks: a 3-hour practical exam (15), project work (10) and a practical file (5). Our ISC Class 12 Biology course follows the CISCE syllabus for the ISC (Classes 11 and 12): reproduction, genetics and evolution, biology and human welfare, biotechnology, and ecology and environment. Lessons are live and one-to-one with a verified subject teacher, who explains each concept clearly, works through textbook and specimen-paper questions with you and shows you how CISCE examiners award marks. It prepares you for the ISC board exam, the practical and the project. Suitable for students in India and at CISCE schools abroad, with lesson times in IST.

Course structure
In short: this course gives one-to-one online tutoring for ISC 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.
ISC Class 12 Biology is part of the Indian School Certificate, the senior secondary qualification set by CISCE (the Council for the Indian School Certificate Examinations). The ISC Class 12 exam is a CISCE board exam, usually held in February and March.
This course covers the full syllabus one to one with a verified biology tutor.
For wider support, see our biology tutoring page, or revisit the foundations in the ISC Class 11 Biology course.
ISC Class 12 Biology follows the CISCE (ISC) syllabus. Class 12 ends with the board examination, set by CISCE, 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 CISCE regulations and syllabus for your exam year. Tutors follow the textbook chapters your school teaches and practise the question styles in recent sample papers.
| Unit | Key topics |
|---|---|
| Reproduction | Reproduction in organisms and 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; enhancement of food production; microbes in human welfare |
| Biotechnology and its applications | Principles and processes; applications in medicine and agriculture |
| Ecology and environment | Organisms and populations; ecosystems; biodiversity and conservation; environmental issues |
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 |
CISCE examiners reward precise answers, correct terminology and neat, well-labelled working. Tutors use your school's textbooks, the CISCE specimen papers and previous years' papers, and teach you to write answers that match the marks allotted. Tutors also help you understand the theory behind your practical experiments and project; the project you submit must be your own work.
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 CISCE syllabus and your school's schedule. See also ISC Class 11 Biology, CBSE Class 12 Biology and our Biology subject page.
The ISC Class 12 Biology syllabus covers reproduction, genetics, biotechnology and ecology, and this course teaches each chapter in live 1-to-1 lessons with diagrams and specimen papers.
This course suits Class 12 ISC students in India and abroad, whatever textbook your school uses.
Prerequisites: ISC Class 11 Biology, including cell biology and human physiology.
Course length: 58 lessons across 15 chapters.
| Stage | Topics | What you can do afterwards |
|---|---|---|
| 1 | Reproduction in organisms, 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; food production; microbes; biotechnology | Explain disease, immunity and biotechnology |
| 4 | Organisms and populations; ecosystem; biodiversity; environmental issues | Explain ecological relationships |
