We cover every major specification. Your tutor matches your board, tier, and mark-scheme language so every lesson points toward exam performance.
The leading international IGCSE Biology syllabus. Core and Extended tiers. Three papers: multiple choice, theory, and practical/alternative to practical.
The updated Cambridge IGCSE Biology syllabus (first exam 2023). Aligned with the new Cambridge framework with refreshed assessment objectives.
Taken by students at British international schools. Two theory papers plus Science in Context. Practical skills assessed through the written papers.

Our tutors build understanding from the cell up — ensuring students can answer both the short-mark and the demanding 6-mark extended response questions.
Step 1
We start with recent marks, confidence blockers, and the exact exam board so sessions feel personal from lesson one.
Step 2
Tutors connect concepts to examiner language, worked examples, and the habits that turn knowledge into marks.
Step 3
Parents see what changed after each session: topics covered, next steps, and the grade trajectory we are building toward.
Plant and animal cell structure, differences, osmosis, diffusion, active transport, and cell division — the foundation for all later biology topics.
Carbohydrates, proteins, lipids, DNA, and enzymes — including how temperature and pH affect enzyme activity with graph interpretation.
Photosynthesis (including limiting factors), digestion, absorption, and the role of each digestive enzyme. Frequently tested with structured data questions.
The heart and circulatory system, double circulation, blood components, and transpiration in plants — including DART diagram interpretation.
Aerobic and anaerobic respiration, the lungs and breathing mechanism, and adaptations of alveoli — essential for understanding cellular energy.
Mitosis, meiosis, monohybrid crosses, codominance, sex-linked inheritance, and genetic mutation — a rich area of Extended-only content.
Food chains and webs, nutrient cycles, population growth, human impacts on the environment, and conservation strategies.

We teach a structured approach: plan the answer before writing, use correct scientific vocabulary, and include examples. Students practise with real past-paper questions and receive mark-scheme-level feedback.
Biology exams include many unfamiliar diagrams. We train students to read axes, identify trends, calculate rates of change, and link data to biological processes — skills that transfer across any graph.
Genetic crosses, Punnett squares, pedigree charts, and codominance are systematically taught with a standard format for all answers. Students who use the right notation never lose presentation marks.
Specialist tutors with board knowledge, strong academic backgrounds, and proven grade-improvement records.

Genetics made no sense until my tutor showed me how to set up every cross the same way. It became the section I actually looked forward to.

The tutor was an actual Cambridge examiner. She showed us the exact phrases that gain marks. We went from Grade 5 to Grade 8 in one term.

Academic Excellence
Families usually want three things: a tutor their child respects, a plan that fits the real paper, and updates that make progress easy to follow.
We shortlist tutors who know the curriculum, teach clearly, and can coach the exact exam habits that lift marks.
Top-university academics and exam-savvy specialists.
Parents see what was covered, what improved, and what needs attention next, so progress never feels vague.
Structured feedback after every lesson block.
Sessions are matched to the student's board, tier, topic gaps, and exam timeline instead of generic subject tutoring.
Board-specific support with a measurable target grade path.
Core covers the fundamental syllabus and gives access to grades C–G (or 1–5). Extended covers the full syllabus and gives access to grades A*–G (or 1–9). We recommend Extended for students who may go on to A-Level or IB Biology.
Extended response questions (typically 4–6 marks) are marked for content points. Each mark requires a correct biological statement or explanation. We teach students to write in bullet points using mark-scheme language, which makes the answer structure clear to examiners.
Yes. Paper 6 (alternative to practical) tests experimental skills in a written format. We cover planning, data recording, analysis, and evaluation using official Cambridge past papers and practical guidance notes.
Genetics is one of our strongest areas. We cover monohybrid and dihybrid crosses, codominance, sex linkage, pedigree analysis, and mutation. We use a consistent notation and layout that matches the mark scheme format.
Yes — particularly at Extended tier. The cellular biology, genetics, and ecology content provides a strong foundation. Students who achieve Grade 7+ at Extended are well prepared to enter A-Level Biology or IB Biology HL.
