IB Biology HL TutoringOne-to-one online preparation for the Biyoloji Higher Level syllabus

Our IB Biology HL tutoring programme fully covers the Biology Higher Level syllabus, one of the most comprehensive and engaging science courses in the IB Diploma Programme. We study living systems from the molecular level to the ecosystem scale with a systematic, holistic approach. Our experienced IB teachers make complex biological processes clear with visual materials, animations and real-world examples.

The core topics span all levels of life. In cell biology we cover cell structure (prokaryotic and eukaryotic), membrane structure and function (the fluid mosaic model, diffusion, osmosis, active transport), cell division (mitosis and meiosis), organelle functions and cell metabolism in depth. We use microscope images, diagrams and 3D models to help cell topics be understood visually.

Molecular biology and genetics are cornerstones of the IB Biology HL syllabus. We systematically cover DNA structure and replication, transcription and translation, regulation of gene expression, Mendelian genetics (monohybrid and dihybrid crosses, linked genes), genetic engineering (PCR, gel electrophoresis, gene cloning, CRISPR) and biotechnology applications. Our teachers teach step-by-step techniques for solving genetics problems.

Evolution and biodiversity provide the historical and ecological context of the living world. We cover the mechanism of natural selection, speciation processes (allopatric and sympatric), phylogenetics and classification, cladograms, and the concepts of homology and analogy in depth. Within ecology we cover population dynamics, community ecology, ecosystem structure, energy flow, food webs and biogeochemical cycles.

HL-specific advanced topics are the critical sections that distinguish IB Biology HL from SL. We cover nucleic acids (the details of DNA replication, telomeres, repair mechanisms), metabolism (the detailed biochemistry of cellular respiration - glycolysis, the Krebs cycle, the electron transport chain; the light and dark reactions of photosynthesis), plant biology (the structure and function of xylem and phloem, plant hormones, tropisms) and advanced genetics (the gene pool, the Hardy-Weinberg principle, genetic drift, gene flow) in depth.

Human physiology is an important component of the IB Biology HL syllabus and is especially valuable for students targeting medicine. We cover the digestive system (enzymes, absorption), the circulatory system (heart structure and function, blood pressure regulation), the immune system (innate and acquired immunity, vaccines, antibodies), the nervous system (neurons, synaptic transmission, the central and peripheral nervous systems), the endocrine system (hormones, feedback mechanisms) and the reproductive system.

The Internal Assessment (IA) project makes up 20% of the IB Biology HL grade and is an important piece of work in which students demonstrate their scientific investigation skills. We provide comprehensive support at every stage of the IA: choosing a research question, forming a hypothesis, defining dependent and independent variables, experimental design, data collection and processing, statistical analysis (t-test, chi-square test, correlation), graphing and scientific report writing. Our experienced teachers teach the strategies needed for top marks.

Our service is fully personalised to the student's level, interests and university goals. A strong Biology HL grade is critical for students targeting careers in medicine, veterinary science, biology, biochemistry, genetics or environmental science. Our programme plans together the content, problem solving and exam strategy a student needs for high goals.
