Your biology tutor - Marwan
"Hello! I'm Marwan, a Medicine graduate and passionate Biology educator with 5 years of tutoring experience across IGCSE, GCSE, A-Level, O-Level, IB, and AP Biology. I believe every student can master Biology with the right guidance and approach. My teaching method has three steps: Connect — I link new material to what you already know. Articulate — I explain exactly why we're learning it. Apply — we practice with real exam-style questions and real-world examples. My medical background gives me a clinically grounded way of teaching technical topics like human physiology, cell biology, and genetics — making them feel real, not abstract. I also completed a summer research program at the University of Rochester, so I bring university-level depth to every lesson. In my own prep, I only consider a concept truly mastered when I can explain it in the simplest possible terms — and that's exactly how I teach it to you. No memorization, no confusion — just real understanding that sticks long after the exam. Every first session starts with figuring out how you learn best — then we build a plan around your goals. Ready to turn confusion into confidence? Book a trial session today and let's get started!

Biology concepts taught by Marwan
The session began with a recap of fundamental biology concepts, including the characteristics of life and themes in biology. The main focus then shifted to the structure and types of chromosomes, defining key terms like histones, genes, chromatids, centromeres, and explaining ploidy (diploid vs. haploid) and different cell division methods (binary fission and cell cycle phases). The Tutor and Student also discussed the study plan for upcoming topics and homework.
Chromosome Structure: Chromatids & Centromeres
Cell Ploidies: Diploid
Haploid
Somatic & Gamete Cells
Human Chromosome Types: Autosomes & Sex Chromosomes
Karyotyping: Chromosome Analysis for Genetic Insight
Cell Cycles: Eukaryotic vs. Prokaryotic Reproduction
Chromosomes: DNA Packaging & Genetic Information
Student and Tutor discussed the student's recent biology quiz, identifying challenges with mitochondria labeling and differentiating between biological cycles. They planned to systematically review foundational biology notes (Units 0-7) and prepare for upcoming final assessments. The session primarily focused on the five characteristics of life (cells, response, homeostasis, consumption, and reproduction), along with core themes in biology such as diversity, interdependence, and evolution, reinforced by a set of practice questions. Homework was assigned to review slides 1-12 and complete a brief assignment.
Stimulus and Response
Themes of Biology: Diversity
Interdependence
Evolution
Heredity
Genetics
& DNA
Homeostasis: Internal Balance
The Student and Tutor reviewed the detailed process of photosynthesis, including its definition, chemical equation, and the various plant cell structures involved. They focused on understanding the light-dependent and light-independent (Calvin cycle) stages and the molecules produced. The Student was encouraged to review the notes, solve practice questions, and utilize AI for further testing to prepare for an upcoming quiz.
Photosynthesis: The Plant's Food Factory
The Chloroplast: Photosynthesis Headquarters
Light-Dependent Reactions: Capturing Sunlight
Calvin Cycle (Light-Independent Reactions): Building Glucose
Stomata & Guard Cells: Leafy Gatekeepers
The Student and Tutor collaborated on a Biology poster assignment, detailing Photosynthesis and Cellular Respiration. They developed chemical equations, descriptions, flow maps, and drawings for key processes such as the Calvin Cycle and electron transport chains. An additional session was scheduled for tomorrow to review specific lecture notes and solve practice questions for an upcoming quiz.
Photosynthesis: Overview and Chemical Equation
Cellular Respiration: Electron Transport Chain
Cellular Respiration: Glycolysis & Krebs Cycle
Photosynthesis: Light-Dependent Reactions & Electron Transport Chain
Cellular Respiration: Overview and Chemical Equation
Photosynthesis: Calvin Cycle (Light-Independent Reactions)
Student and Tutor had an extensive biology session focused on cellular respiration. They reviewed key definitions, the distinction between aerobic and anaerobic respiration, the three main stages (glycolysis, Krebs cycle, and electron transport chain), and the specific locations and products of each stage within the cell and mitochondria. The Student has an upcoming quiz on notes 6 and 7 (photosynthesis and cellular respiration), and the Tutor recommended memorizing key terms and a summary table for the next session. They also adjusted future session timings.
Cellular Respiration Fundamentals
Electron Transport Chain (ETC): The Major ATP Producer
Krebs Cycle (Citric Acid Cycle)
Glycolysis: The Initial Glucose Breakdown
Mitochondrial Structure & Role
The Student and Tutor began by discussing the Student's recent biology exam, covering questions related to genetics, DNA analysis, and interpreting scientific graphs. They then focused on an upcoming school unit, outlining the syllabus for the next week which includes cellular respiration and potentially mitosis/meiosis. The Tutor introduced the foundational concepts of cellular respiration, including ATP, aerobic, and anaerobic processes, and assigned reviewing the provided material and observing the school's lesson for comparison.
