Ajay Vatsyayan Classes provides one-to-one biology home tuition in Gurgaon for Classes 9 to 12, for CBSE, ICSE, ISC, Cambridge IGCSE and the IB Diploma, and for NEET (UG). A tutor from our Home Tutors Team teaches at your home or in live online classes, follows your child's school syllabus chapter by chapter, and adds NEET practice where it is needed. You meet the tutor in a free demo class before you decide.
We have taught in Gurgaon (Gurugram) for 12+ years, with 25,000+ students, 500+ verified tutors and families from 50+ Gurgaon schools. For the full NEET plan across all three sciences, see our NEET home tutors in Gurgaon page.
Every session is one tutor with one student, at home or online. The tutor starts with a short diagnostic, writes a plan around the school calendar, and then teaches in a steady weekly cycle.
Biology rewards precise words and clean diagrams, so our tutors teach the exact term, then the idea, then the labelled diagram.
Each board examines biology differently. The table sets out the official structure for students in school in 2026–27.

| Board and course | Classes | How biology is examined | What to watch |
|---|---|---|---|
| CBSE Science (Class 9–10) | 9–10 | Part of one Science paper. Class 10: 80-mark, 3-hour board paper plus 20 internal; biology carries 30 of the 80 marks | Class 9 uses the new NCERT textbook Exploration from 2026–27 |
| CBSE Biology (044) | 11–12 | 70-mark, 3-hour theory paper plus 30 marks of practicals, including a project | Class 11 is examined by the school; Class 12 is the board exam |
| ICSE Science: Biology | 9–10 | A separate Biology paper: 2 hours, 80 marks, plus 20 marks of internal practical work | Diagrams and exact definitions carry many marks |
| ISC Biology (863) | 11–12 | 70-mark, 3-hour theory paper; practical exam 15, project 10, practical file 5 | CISCE asks for all structures to be taught "along with diagrams" |
| Cambridge IGCSE Biology (0610) | 9–10 (Years 10–11) | Three papers: multiple choice (40 marks, 45 minutes, 30%), theory (80 marks, 1 hour 15 minutes, 50%), and a practical test or alternative to practical (40 marks, 20%) | Core or Extended tier; only Extended can lead to grades A* and A |
| IB Diploma Biology | 11–12 | SL (150 teaching hours) or HL (240 hours); external papers plus one scientific investigation as internal assessment (20%) | Four themes: unity and diversity, form and function, interaction and interdependence, continuity and change |

Classes 9 and 10 build the vocabulary for everything after them: the cell, tissues, life processes, reproduction and heredity. Gaps here resurface in Class 11.
In CBSE Class 9 (2026–27), science uses the new NCERT textbook Exploration, and the World of Living unit carries 27 of the 80 theory marks. In Class 10, biology comes from two units: World of Living (25 marks: life processes, control and coordination, reproduction and heredity) and Natural Resources (5 marks: our environment). In CBSE's 2026–27 sample paper, biology is Section A. Evolution is taught again but assessed only in school, not in the board exam. Our guide to the CBSE Class 10 Science syllabus 2026–27 lists every chapter, and our Class 9 tuition in Gurgaon and Class 10 tuition in Gurgaon pages cover the other subjects.
ICSE treats biology as its own paper. For the 2027 exam, Class 9 covers basic biology, flowering plants, plant physiology, diversity, human anatomy and physiology, health and hygiene, and waste management. Class 10 covers cell division and genetics, plant physiology, human anatomy and physiology, population, human evolution and pollution. Our tutors set labelled-diagram drills every week.
Cambridge IGCSE Biology has 21 topics, from the characteristics of living organisms to biotechnology and genetic modification. Paper 5 or 6 tests experimental skills, so students practise planning investigations and reading data, not just recalling facts.

| Unit | Class | CBSE 2026–27 (of 70) | ISC 2027 (of 70) |
|---|---|---|---|
| Diversity of Living Organisms | 11 | 15 | 9 |

| Plant Physiology | 11 | 12 | 17 |

| Reproduction | 12 | 16 | 16 |
| Genetics and Evolution | 12 | 20 | 15 |

From our tutors: the Class 11 student who struggles in biology is rarely short of effort. Usually they are reading and highlighting, which feels productive but builds little recall. We replace it with one habit from the first month: close the book, draw the diagram or flow chart from memory, then check it against the textbook and correct it in a different colour. Plant physiology and human physiology become much lighter once students do this.
Biology is half of NEET. In NEET (UG) 2026, it had 90 of the 180 questions (Botany and Zoology) and 360 of the 720 marks, in a 3-hour pen-and-paper exam marked +4 for a correct answer and −1 for a wrong one. Biology is also the first tie-breaker. The National Medical Commission's NEET (UG) 2026 syllabus has ten biology units with the same names as the Class 11 and 12 board units. Source: the NEET (UG) 2026 Information Bulletin on neet.nta.nic.in, checked on 30 September 2026.
No 2027 bulletin or syllabus had been published when we checked, so the 2027 mode and pattern are not confirmed. Our tutors plan on the 2026 syllabus and practise on paper and on screen.
Our ISC vs CBSE for JEE and NEET guide compares the two boards line by line. For the other two NEET subjects, see our NEET physics tutor in Gurgaon and NEET chemistry home tuition in Gurgaon pages, and our physics tuition in Gurgaon and chemistry tuition in Gurgaon pages.
From our tutors: most NEET biology marks are lost not on hard questions but on options that are nearly right: a swapped word, a wrong example, a correct statement about the wrong organism. We ask students to say why each wrong option is wrong, not just pick the right one. Within a few weeks they start spotting the trap themselves, and careless negatives fall.
Genetics is the largest CBSE Class 12 unit (20 marks). Both examples were checked by calculation.
Cross two pea plants heterozygous for seed shape and colour: RrYy × RrYy. Each parent makes four kinds of gametes (RY, Ry, rY, ry), giving 16 equal combinations.
Phenotypes: round yellow 9, round green 3, wrinkled yellow 3, wrinkled green 1, the ratio 9 : 3 : 3 : 1.
Only RRYY breeds true for both traits, and it appears in 1 of the 16 boxes.
Answer: 1 of the 9 round, yellow offspring, so 1/9 (and 1/16 of all offspring). Common error: answering 1/16 when the question asks about the round, yellow plants only.
The recessive phenotype is aa, so q² = 0.16 and q = 0.4.
Then p = 1 − q = 0.6.
Carriers (Aa) = 2pq = 2 × 0.6 × 0.4 = 0.48, and AA = p² = 0.36. Check: 0.36 + 0.48 + 0.16 = 1.
Answer: 48% are carriers. Common error: taking q = 0.16, which confuses the genotype frequency with the allele frequency.
You can ask for a male or female biology tutor. We do not promise marks; we promise the current syllabus, a clear plan and honest feedback after every test.

Classes 9 to 12 for CBSE, ICSE, ISC, Cambridge IGCSE and the IB Diploma (SL and HL), and NEET (UG) for Class 11, Class 12 and drop-year students.
Yes. The tutor teaches the school chapter first, then adds NEET-style timed questions on the same chapter. For the full three-subject plan, see our NEET home tutors in Gurgaon page.
NCERT Class 11 and 12 Biology is the base, because NEET questions often follow its wording. Neither NTA nor the NMC publishes chapter weightage, so cover every line of the NMC syllabus and practise timed questions too.
Yes. The NEET (UG) 2026 bulletin accepts ISC and other recognised boards with Physics, Chemistry, Biology or Biotechnology and English. ISC and IGCSE students should add NCERT reading, since NEET follows NCERT closely.
One-to-one home tuition with us usually costs ₹600 to ₹3,000 per hour depending on class, board and subject. Our guide to home tuition charges in Gurgaon explains what is fair.
