Exam-Style Practice Papers with Worked Solutions

Original practice questions written to the KCSE, GCSE, A-Level, IGCSE and SAT syllabuses, every one worked through with the marking points explained. Free to read. Or create a free account to upload a paper of your own for an instant walkthrough.

These are original practice questions written by StudyAI in the style of the syllabus named. They are not copies of any real examination paper, and are not affiliated with or endorsed by any examination board. Mark allocations mirror how the board typically awards marks so the practice is realistic.

KCSE 6 papers

Biology 40 marks · 75 min

Practice Paper 1

Short-answer practice across homeostasis, photosynthesis, cell division, digestion and gaseous exchange, each with the marking points and the mistake that loses them.

Chemistry 40 marks · 75 min

Practice Paper 1

Structure of the atom, bonding, moles and stoichiometry, acids and bases, redox and organic chemistry — worked with the working shown the way markers expect it.

View solutions →
Mathematics 50 marks · 90 min

Practice Paper 1

Algebra, surds and indices, geometry, trigonometry and statistics, worked line by line so you can see exactly where the method marks sit.

View solutions →
Physics 40 marks · 75 min

Practice Paper 1

Mechanics, pressure, thermal physics, waves, electricity and radioactivity — every answer carried through with units, because units are marks.

English 40 marks · 80 min

Practice Paper 1

Functional writing, cloze, oral skills and grammar — including the minutes layout mark by mark, since format is where most of the writing marks actually are.

View solutions →
Business Studies 40 marks · 75 min

Practice Paper 1

Office practice, demand and supply, forms of business, book-keeping, transport and government finance, with the command words that decide how much to write.

GCSE 3 papers

Biology 45 marks · 75 min

Practice Paper 1

Cell biology, organisation, infection and response, and bioenergetics, including the 4- and 6-mark extended responses and what a full-marks answer contains.

View solutions →
Mathematics 40 marks · 60 min

Practice Paper 1 (non-calculator)

A non-calculator set covering number, algebra, ratio, geometry and probability, with the method marks called out separately from the accuracy marks.

View solutions →
Chemistry 45 marks · 75 min

Practice Paper 1

Atomic structure, bonding, moles and energy changes, including the four-step mass calculation where most of the grade 7-9 marks are won and lost.

View solutions →

A-Level 2 papers

Chemistry 45 marks · 75 min

Practice Paper 1

Organic mechanisms, equilibria, kinetics and thermodynamics, with the curly arrows drawn correctly and the marks that depend on them made explicit.

View solutions →
Mathematics 50 marks · 90 min

Practice Paper 1

Differentiation, integration, series, binomial expansion, trigonometry and proof by contradiction, with M, A and B marks separated as the real mark scheme separates them.

View solutions →

SAT 2 papers

Math 22 marks · 35 min

Practice Set 1

Algebra, advanced maths, problem solving and data analysis, and geometry — each with the fast route as well as the full one, since the SAT is timed tightly.

View solutions →
Reading & Writing 14 marks · 20 min

Practice Set 1

Words in context, text structure, command of evidence, transitions and conventions, each with the elimination logic that gets there fastest.

View solutions →

IGCSE 1 paper

Physics 40 marks · 70 min

Practice Paper 1

Motion, forces, energy, thermal physics, waves and electricity, written to Cambridge command words so the answers are the right shape as well as correct.

View solutions →

CBSE 2 papers

Mathematics 40 marks · 90 min

Practice Paper 1

Real numbers, polynomials, linear equations, triangles, trigonometry and statistics, with the step marks shown separately because CBSE awards them separately.

View solutions →
Physics 35 marks · 75 min

Practice Paper 1

Electrostatics, current electricity, magnetism, induction and optics, with derivations laid out the way CBSE awards marks for the principle, the diagram and the steps.

View solutions →

NEET 1 paper

Biology 60 marks · 16 min

Practice Set 1

Cell biology, plant and human physiology, genetics and ecology in NEET format, with every distractor explained because elimination is what negative marking rewards.

View solutions →

JEE Main 1 paper

Physics 48 marks · 40 min

Practice Set 1

Kinematics, rotation, thermodynamics, current electricity and modern physics at JEE difficulty, with the standard result given alongside the full derivation.

View solutions →

ACT 1 paper

Science 12 marks · 15 min

Practice Set 1

Data representation, research summaries and conflicting viewpoints — a section that tests reading graphs under time pressure far more than it tests science.

View solutions →

AP 2 papers

Biology 16 marks · 30 min

Practice Set 1

Cell structure, energetics, gene expression and evolution, plus a scored free-response question — because AP rewards explaining mechanisms, not naming them.

View solutions →
Calculus AB 18 marks · 35 min

Practice Set 1

Limits, derivatives, applications and the Fundamental Theorem, with the setup and notation points separated out the way AP free response actually scores them.
