In this module I tutor in biology on a middle school to high school to college level, depending on what is required by the student. The possibilities vary from simple lessons about basic concepts all the way to the topics needed to pass ''end exams'' like the SAT, GCSE, MCAT and International Baccalaureate. My knowledge from medical school help me explain the material on a deeper level if the student requires so.

I'm a Biology tutor. Biology isn’t just a subject—it’s the story of life itself for me. From the tiniest cell to the largest ecosystem, I bring the fascinating world of living things to life in every class. With a passion for teaching and a love for discovery, I simplify complex concepts and turn them into exciting, understandable lessons that stick. Whether we're exploring the human body, decoding DNA, or understanding how plants breathe, I make sure every session feels like a mini-adventure. As a dedicated biology teacher, I believe learning should be both educational and enjoyable. I use real-life examples, interactive visuals, and curiosity-driven questions to keep students engaged and motivated. My goal is not just to teach facts, but to spark a lifelong interest in science. I adapt my teaching style to match each student’s pace and learning preference, ensuring no one is left behind and everyone feels confident to ask “why” and “how.” Join me to see how biology connects to your everyday life in surprising and inspiring ways. Whether you're preparing for exams, building a strong science foundation, or just love learning about life, my classes are designed to make biology clear, exciting, and fun. Let’s explore the wonders of life together—one cell, one organ, and one discovery at a time!

In the IGCSE and CIE (Cambridge International Education)curricula, Genetics is a part of Biology under the broader topics of inheritance and variation. It is covered in both IGCSE Biologyand AS/A Level Biology. Below is a breakdown of what you can expect in each: IGCSE Biology (Cambridge - 0610/0970) The topic of genetics is introduced under the following key areas: 1. Variation and Inheritance - Genetic variation: Understanding differences caused by genetic and environmental factors. - Inheritance: - Definition of key terms: genes, alleles, dominant, recessive, homozygous, heterozygous, phenotype, genotype. - Monohybrid inheritance (using Punnett squares to predict offspring ratios). - Concepts of dominant and recessive traits. - Structure of DNA: - Basic structure of DNA (double helix) and its role in carrying genetic information. - Mutations: - Causes (e.g., radiation, chemicals) and effects of mutations on organisms. 2. Selective Breeding and Genetic Engineering (basic concepts): - Selective breeding in animals and plants to produce desired traits. - Introduction to genetic modification (GM), though details are limited in IGCSE. --- CIE AS and A Level Biology (9700) At the A Level, genetics is covered in greater depth. Key concepts include: 1. DNA and Protein Synthesis: - Structure of DNA, RNA, and nucleotides. - Transcription, translation, and protein synthesis. - Genetic code and its universal nature. 2. Cell Division: - Mitosis and meiosis. - Significance of meiosis in genetic variation (crossing over, independent assortment). 3. Inheritance: - Mendelian genetics: monohybrid and dihybrid crosses. - Codominance and multiple alleles. - Sex-linked inheritance (e.g., haemophilia, color blindness). - Pedigree analysis. 4. Gene Technology: - Recombinant DNA technology (genetic modification and cloning). - Applications of genetic engineering in medicine and agriculture. 5. Mutations: - Gene mutations and their effects. - Chromosomal abnormalities. 6. Variation and Selection: - Natural selection and evolution. - Role of genetic variation in populations. --- Summary - At the IGCSE level, genetics focuses on basic concepts of inheritance, variation, DNA structure, and simple Punnett square problems. - At the AS/A Level, the depth increases significantly, introducing advanced topics like meiosis, protein synthesis, genetic engineering, and natural selection.

Who among you has visited a mountain or seen rocks of different colors and shapes? Why do you think the rocks are different? Let's find out together! 1. Igneous rocks: They are formed by volcanoes after magma (lava) cools. An example from the Saudi environment: the Harrat Rahat rocks south of Medina. Appearance: dark, hard, and perforated. 2. Sedimentary rocks: It is formed by the accumulation of layers of sand and clay over time. Local example: Rocks in the Great Nafud Desert. Its shape: clear layers, easy to crumble. 3. Metamorphic rocks: It is formed by the alteration of other rocks due to pressure and heat. Example: Metamorphic granite rocks in the Hejaz Mountains. Its shape: its colors are intertwined and strong.

My name is Younes and I give language lessons, for me teaching means learning twice so my learning method is based on simplicity and above all you have to move forward according to the student's rhythm to allow him to learn. improve and acquire new bases and be able to assimilate new information without ever becoming saturated. Sometimes it's better to go slowly but surely. In addition, I am a young researcher in applied biochemistry and a temporary teacher at the university for 4 years, so for those who have difficulties and gaps in biochemistry, I will be there to simplify you and above all to make you discover the world. wonder of biochemistry and thank you for stopping by.

Doctor in chemical sciences with extensive professional experience in the life sciences, I help upper secondary, university and higher education students to approach and understand chemistry, organic chemistry, and biochemistry. I emphasize an understanding of basic concepts from experience in other areas of interest to the student. I also help with the preparation and writing of internship reports, ITTs and doctoral theses.
