High School (11–12) Biology

Beyond the textbook: reading spirometer graphs of healthy and diseased lungs, working out ventilation and dead space, calculating partial pressures and the oxygen carried by blood, and reasoning about every shift of the dissociation curve. Twelve harder problems and a full timed mock exam.

Beyond the textbook: a full account of the ATP, NADPH, carbon and photons that photosynthesis spends, a point-by-point comparison of the C3 and C4 pathways, and the reading of limiting-factor graphs and classic experiments. Twelve harder problems and a full timed mock exam.

Beyond the textbook: how proteins fold and why shape means function, and Michaelis-Menten kinetics with the Lineweaver-Burk plot. Then competitive and non-competitive inhibition by numbers, and how pathways are controlled by feedback, with a full timed paper.

The plant groups side by side, with their key examples, economic uses and the tricky points that exams test, worked step by step, and a full NEET-style mock exam.

Two kinds of bacteria can differ from each other as much as a bacterium differs from you. How do biologists know? In this course we read three ideas that the main chapter only touches: the three domains of life, how bacteria are stained, grown and counted in a laboratory, and how a virus takes over a cell. Then we solve harder problems at the level of NEET, AP Biology and A-Level Biology, and take a timed test.

A horse and a donkey can have a young one, the mule, and the mule cannot have young. So are the horse and the donkey one species or two? In this course we read three ideas that the main chapter only touches: what a species really is, the finer rules that give each species one name, and how a key and a DNA barcode find a name. Then we solve harder problems at the level of NEET, AP Biology and A-Level Biology, and take a timed test.
