aleph is an exam preparation platform built on continuous feedback. Three subjects in parallel. A 15-day adaptive cumulative review that resurfaces weak concepts and fades mastered ones. Every quiz exposes your gaps. You don't move forward until the system is sure you understand.
No credit card required. Start with free problem sets.
Three subjects progress in parallel. You don't finish one before starting the next.
Concise, rigorous material. No fluff. No 40-minute videos.
Concept, integration, and challenge problems. Each set is calibrated to the section's difficulty.
Demonstrate understanding to unlock the next section. Fall short? Get a targeted review quiz and retry.
Concept graphs track dependencies across subjects. Weak on combinatorics? The system knows and adapts.
Most platforms tell you your score. aleph tells you exactly what to fix.
Every quiz question maps to a specific concept node. Get one wrong? The system traces the dependency graph and tells you exactly which prerequisite to review — not just "you got 3 wrong."
Every 15 days, a review quiz surfaces weak concepts, skips mastered ones, and brings back high-weight exam topics. No two students see the same quiz — it adapts to your actual performance graph.
The concept graph tracks mastery across all topics. Green nodes mean you own it. Red nodes mean it needs work. Gray nodes mean you haven't reached it yet. No more studying what you already know.
Each course is a complete roadmap from fundamentals to exam-level problems. Applicable across GATE DA, ISI, CMI, and other quantitative exams.
Chapters 1–10. Combinatorics through expectation and inequalities. Labelled practice problems with full worked solutions.
Chapters 1–4. Matrices, eigenvalues, vector spaces, and linear transformations. Structured for exam depth.
Every problem set passes a 6-dimension quality rubric. Explanations are banned from using "clearly," "obviously," or "trivially." Solutions show every step. No hand-waving. No skipped algebra.
