Ten questions on heat, work and the first law: signs of heat and work, a piston, a gas's internal energy, a cycle on a pressure-volume graph, Joule's paddle wheel and a free expansion. Every answer has a worked solution that names the usual slip.
Ten questions on entropy, Gibbs energy and spontaneity. Untimed.
Ten questions on the compound angle, multiple angle and sum-to-product formulae. Untimed.
Ten questions on diffusion, osmosis, turgor and plasmolysis, and active transport. One asks you to find a mistake. Every answer has a worked solution that names the usual slip.
Ten questions on the range, the interquartile range, the variance and the standard deviation, and on what happens to them when every value changes. One reads a box plot. Every answer has a worked solution that names the usual slip.
Ten questions on heat: warming water, mixing, a copper block in water, melting ice, steam burns, a kettle, a calorimeter and ice in a drink. Every answer has a worked solution that names the usual slip.

Ten questions on composition, one-one and onto functions, inverses and simple models. One asks you to choose a graph. Every answer has a worked solution that names the usual slip.
Ten questions on pressure and floating: a swimming pool, a garage lift, a diver, a water barometer, three vessels of different shapes, a stone under water, an iceberg and a ship that sails into the sea. Every answer has a worked solution that names the usual slip.
Ten questions on Lewis structures, ionic bonds and bond parameters. Untimed.
Ten questions on graphs, the modulus and greatest-integer functions, shifts and stretches, and even and odd functions. One asks you to choose a graph. Every answer has a worked solution that names the usual slip.
Ten questions on satellites: orbital speeds and periods, the energy of an orbit, geostationary satellites, weightlessness and a scale in a lift. Every answer has a worked solution that names the usual slip.
Ten questions on molecular mass, formula unit mass, the mole and the Avogadro constant, and the mass of one molecule. Every answer has a worked solution that names the usual slip.
Ten questions on field, potential and escape: field strength, a satellite's energy, lifting a payload, a hollow sphere, escape speeds, and a probe fired straight up. Every answer has a worked solution that names the usual slip.
Ten questions on Kepler's laws and gravity: a long year, a comet's orbit, two students, a probe above the Earth, a deep mine, a graph of g to choose, weighing the Earth and a bigger planet. Every answer has a worked solution that names the usual slip.
Ten questions on angular momentum, balance and rolling: a turntable, a skater, a seesaw, a loaded plank, a rolling disc's energy split to choose, and a race down a slope. Every answer has a worked solution that names the usual slip.
Ten questions on torque and moment of inertia: a cross product, a door, a ring, a disc, a swinging rod, a flywheel and a bucket on a well. Every answer has a worked solution that names the usual slip.
Ten questions on the centre of mass and turning: weights on a table, a rod with two balls, an L-shaped plate, an astronaut and a toolbox, skaters on a rope, a firework, a fan, a potter's wheel and a grinder. Every answer has a worked solution that names the usual slip.
Ten questions on power and collisions: stairs, a car engine, the electricity bill, a pump, trolleys that stick, billiard balls, a bouncing ball, a ballistic pendulum and pucks on an air table. Every answer has a worked solution that names the usual slip.
Ten questions on potential energy and its conservation: a shelf, a spring's energy graph to choose, a water slide, a roller-coaster track, a pendulum, a toy launcher and a playground slide. Every answer has a worked solution that names the usual slip.
Ten questions on work and kinetic energy, set in everyday scenes: a bag carried along a corridor, a suitcase, two vectors, a sliding box, a cricket ball, a braking car, a stopping distance, a force graph and a spring. Every answer has a worked solution that names the usual slip.
Ten questions on friction and circular motion: a friction graph to choose, a trunk, a dragged box, walking, a tilted book, an icy slope, a ramp, a flat bend and a banked curve. Every answer has a worked solution that names the usual slip.
