From first steps to doctoral study
Start slowly. Each stage builds on the previous one; later branches have their own prerequisites. The foundation lessons are available now. The remaining curriculum is a plan for future lessons, not a complete course.
1. First steps · FOUNDATION LESSONS AVAILABLE
Before you start: No prior chemistry; everyday reading and counting.
Observations, matter, particle models, formulas, atoms, ions, and introductory calculations. Mathematics is introduced or linked before use.
Ready to continue when you can: Distinguish observation from interpretation and explain a formula or calculation in words.
Start the foundation lessons →2. School foundations · PLANNED
Before you start: First-step chemistry and basic algebra.
Moles and stoichiometry in depth, bonding, periodic patterns, gases, solutions, energy changes, equilibrium, and acids and bases.
Ready to continue when you can: Track atoms, charge, quantities, and units through a multistep problem.
3. Undergraduate core · PLANNED
Before you start: School chemistry; algebra, calculus, and introductory physics as required.
General, organic, inorganic, analytical, and physical chemistry, with supervised measurement, uncertainty, and laboratory practice.
Ready to continue when you can: Interpret evidence from measurements, justify a proposed mechanism or model, and write a reproducible report.
4. Advanced undergraduate study · PLANNED
Before you start: Core chemistry and the mathematics required by the selected topic.
Spectroscopy, thermodynamics, kinetics, quantum chemistry, synthesis planning, instrumental analysis, and scientific computation.
Ready to continue when you can: Combine multiple forms of evidence, evaluate alternatives, and quantify uncertainty.
5. Graduate foundations · PLANNED
Before you start: Advanced core study plus relevant experimental or computational experience.
Advanced theory and methods chosen for a branch: organic, inorganic, physical, analytical, materials, chemical biology, or computational chemistry.
Ready to continue when you can: Critically read research papers and defend method selection and limitations.
6. Research specialization · PLANNED
Before you start: Relevant graduate methods and supervised practical competence where needed.
A focused literature review, specialist instruments or computational methods, validation, controls, and reproducibility.
Ready to continue when you can: Reproduce and critically evaluate a published result; design controls for a bounded research question.
7. Doctoral research practice · PLANNED
Before you start: Specialist knowledge and appropriate research supervision and facilities.
Original research design, evidence synthesis, method development, responsible data handling, publication, and thesis defence.
Ready to continue when you can: Produce and defend a new, well-supported contribution, including negative results and limits of inference.
Doctoral-level work involves specialization, original research, and expert critique. This pathway supports that preparation; completing site lessons does not confer a degree or establish research competence.
Experimental chemistry also requires supervised laboratory training and appropriate facilities. Reading and calculation exercises cannot replace that experience.
