University mathematics online — built around the exam
MathKiller is the most complete adaptive learning platform for Israel’s university mathematics courses. Structured lessons, thousands of practice questions and step-by-step guided solutions — all in one place.
Every Open University math course
We cover every core course: Linear Algebra 1 (20109), Linear Algebra 2 (20229), Calculus 1 (20474), Calculus 2 (20475), Statistics A, Statistics B and Probability & Statistics (20425). Each course follows the official syllabus exactly, broken into units and short, finishable lessons.
Practice on the real exams
Thousands of questions pulled from real past papers — first sitting, retake and third sitting — tagged by unit and by difficulty. Every one comes with a step-by-step guided solution, hints that unlock as you get stuck, and the common traps flagged. Plus full exam simulations for every course and practical exam-prep tactics.
Lessons, formula sheets and theorem lists
Every course ships with unit-by-unit summaries, a complete formula sheet and a theorem list carrying the exact statements you are expected to quote. Rigorous where it matters, with intuitive explanations, detailed examples and visuals alongside. Ideal for a night-before review or for meeting new material cold.
Adaptive learning that shapes itself around you
The engine watches how you actually perform and builds practice made for you — more time on your weak spots, less on what you already own. Daily challenges, streaks, crowns and XP keep the momentum going for a whole semester. Unlimited free practice.
Made for Open University of Israel (OUI) students, for students at every other Israeli university, and for high-schoolers taking the advanced maths finals. Study online, on your schedule, from any device — laptop, tablet or phone.

What is MathKiller?
MathKiller is an adaptive learning platform for university mathematics in Israel. It covers Linear Algebra 1 (20109), Linear Algebra 2 (20229), Calculus 1 (20474), Calculus 2 (20475), Statistics A, Statistics B and Probability & Statistics (20425) — with short lessons, thousands of fully worked practice questions, formula sheets, theorem lists and sample exams.
Which courses are on the site?
Right now: Linear Algebra 1 (20109), Linear Algebra 2 (20229), Calculus 1 (20474), Calculus 2 (20475), Statistics A, Statistics B and Probability & Statistics (20425). Every course carries the full syllabus, lessons ordered by unit, thousands of solved exercises and sample papers from previous sittings.
Does MathKiller match Open University course 20475 (Calculus 2)?
Yes. The course is mapped precisely onto the 20475 syllabus: definite and indefinite integrals, integration by parts and substitution, partial fractions, improper integrals, numerical series, convergence tests, power series, Taylor series, sequences and series of functions, and multivariable calculus. There are 45+ lessons, 3,000+ solved questions and exam-level questions from the first, second and third sittings.
Does MathKiller match course 20229 (Linear Algebra 2)?
Yes. Linear Algebra 2 (20229) covers inner product spaces, orthogonality, Gram-Schmidt, the adjoint operator, unitary operators, the spectral theorem, quadratic and bilinear forms, Sylvester's law, polynomials of operators, triangularization, Cayley-Hamilton, the primary decomposition and Jordan form — in the same order, split across the same 11 Open University units.
Are the questions from real exams?
Yes. Every course carries hundreds of questions taken from previous Open University sittings, tagged by unit and by difficulty, each with a step-by-step guided solution, progressive hints and a quick-recognition tip for exam day. First, second and third sittings are all included.
Is the site free?
Practice on the site is free right now. Any future paid tier will apply only to advanced material. You can start immediately — no credit card needed.
How does the adaptive learning work?
The system tracks the questions you miss alongside the ones you nail, and builds a review list aimed at your weak spots. The more you practise, the closer the questions sit to your actual level — focused work where you need it, no pointless repetition of what you already know. Daily challenges, streaks and XP keep the motivation up.
Does every question have a worked solution?
Yes. Every question comes with an ordered step-by-step solution, hints that unlock as you get stuck, and the common mistakes called out. There are also unit-summary lessons that gather all the formulas and theorems of a unit in one place.
Are there formula sheets and theorem lists?
Yes. Every course has a full formula sheet and a theorem list you can review before an exam. Advanced courses such as Linear Algebra 2 carry 135+ formulas organised by unit and more than 50 key theorems with their exact statements.
My exam is in a week — where should I start?
Open your course page and hit "exam practice" to see how many exam questions each unit has. Start with the units where your progress is lowest, finish their summary lessons, then move on to full exam simulations. Run through the formula sheet and the theorem list the day before.
Is the course content in Hebrew or English?
The lessons, solutions and practice questions are written in Hebrew, because they follow the Hebrew-language syllabi of the Open University of Israel and the University of Haifa. This English page explains what the platform does; the mathematics itself — formulas, notation and diagrams — is universal, and many international students use the site alongside their own materials.
