Past papers and chapter breakdown are currently being added. 15+ Smart Tools (Atom Builder, Quadratic Solver, Molar Mass) available now!
Smart Tools & Science Simulations
Stop memorizing abstract diagrams. Manipulate ray mirrors, balance chemical equations, inspect atom shells, and solve equations interactively.
Build an Atom
Construct atoms with protons, neutrons, and electrons.
Chemical Equation Balancer
Balance equations and see how atoms are conserved.
Unit Converter
Convert the units used most in Pakistani board Mathematics, Physics, and Chemistry.
Algebra & Quadratic Solver
Solve linear and quadratic equations with formula substitution and roots.
Reflection & Spherical Mirrors (Unit 13)
Explore the laws of reflection, plane mirror geometry, and all six concave-mirror image-formation cases with a draggable object and live ray diagrams.
Dispersion of Light (VIBGYOR Prism)
Explore the splitting of white light into 7 constituent colors through a glass prism and raindrop rainbow formation.
Structured Study
Turn scattered exam prep into consistent progress.
Traditional rote learning leaves students unprepared for changes in board paper patterns. EzyPreps builds deep mastery from first principles.
Select your board & class
Start with BSEK Karachi, Federal Board (FBISE), or provincial boards for Class 9 through 12.
Target high-frequency exam topics
Prioritize questions that examiners repeat most often, complete with verified solutions and mark schemes.
Test under exam conditions
Run timed MCQ simulations or use visual tools to master difficult science concepts before exam day.
