Organic Chemistry is a STEM Subject and it is very important if you are preparing for AP, O Level, MCAT, CBSE, NEET, JEE Mains exams. You will get a detailed analysis of Concepts and Previous Years Questions from Org Chem. All your concepts will be crystal clear after taking the class.

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 have experience in teaching in secondary education (ASO/TSO) and higher education and have been providing tutoring for more than 10 years. If you want to improve your basic knowledge of sciences (chemistry, biology, biochemistry, cell biology, inorganic chemistry), then you have come to the right place.

In my classes, I use the curriculum provided to ensure we cover everything you need to know, going in-depth into each topic to make sure no detail is overlooked. My teaching approach revolves around pinpointing weak areas through targeted questioning, helping you understand concepts at a deeper level. I believe in the power of active recall and use it as a core strategy to enhance memory retention. By engaging in this active learning method, you'll be able to retain information more effectively and feel more confident when exam time arrives. Whether you're struggling with specific topics or looking to enhance your understanding of the subject, my classes will guide you through each concept and ensure you're fully prepared for success.

In the CIE (Cambridge International) curriculum, Biochemistry is primarily covered in Biology and partially in Chemistry at both IGCSE and AS/A Level. It focuses on the chemical processes and molecules essential for life. Here's a detailed overview: IGCSE Biology (0610/0970) Biochemistry at the IGCSE level introduces students to basic biological molecules and processes: 1. Biological Molecules - Carbohydrates: - Monosaccharides (e.g., glucose), disaccharides (e.g., sucrose), and polysaccharides (e.g., starch, glycogen). - Role in energy storage and release. - Proteins: - Made up of amino acids. - Functions: enzymes, structural components (e.g., keratin), and hormones. - Lipids: - Fats and oils: composed of fatty acids and glycerol. - Role in energy storage, insulation, and cell membranes. 2. Enzymes - Biological catalysts that speed up reactions. - Factors affecting enzyme activity: temperature, pH, and substrate concentration. 3. Photosynthesis - Biochemical process in plants to produce glucose using light energy, carbon dioxide, and water. - Equation: 6CO2 + 6H2O → C6H12O6 + 6O2. 4. Respiration - Aerobic respiration: Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP). - Anaerobic respiration in humans: Glucose → Lactic acid + Energy. 5. DNA and Protein Synthesis (Basic level) - DNA as the molecule of inheritance. - Role of DNA in carrying genetic information. --- CIE AS and A Level Biology (9700) At the AS/A Level, biochemistry is studied in depth. Key areas include: 1.

Molecular Biology - DNA replication, transcription, and translation. - Role of mRNA, tRNA, and ribosomes in protein synthesis. 6. Biochemical Processes in Cells - Role of ATP in metabolism. - Metabolic pathways and enzyme regulation. --- CIE AS and A Level Chemistry (9701) While biochemistry is primarily a biology topic, it also features in chemistry at A Level: 1. Amino Acids and Proteins - Structure of amino acids and peptide bonds. - Protein hydrolysis and analysis. 2. Carbohydrates - Structure of glucose and its isomers. - Reactions of carbohydrates (e.g., oxidation). 3. Lipids - Structure of triglycerides, fatty acids, and phospholipids. - Saponification and ester formation. 4.

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.
