Eight entrance exams, fully solved & tagged
Every single past question sits under its real chapter and topic, so you can drill exactly what you keep losing marks on.
The difference
The solution is the product
Most sites put “Download Free PDF” in the heading and a signup wall on the file. We wrote out the working for essentially every question in the bank — and it is there before you make an account.
Worked, not just keyed
An answer key tells you that you were wrong. A solution tells you where.
Tagged to the syllabus
561 chapters across 51 subjects, so weak areas are findable.
Checked, and honest about it
Questions are AI-verified and then reviewed by our content team before anything changes.
If the nth term of an AP is an = 3n + 2, what is the sum of the first 20 terms?
Solution
a₁ = 3(1) + 2 = 5, and a₂₀ = 3(20) + 2 = 62.
S₂₀ = 20/2 × (5 + 62) = 10 × 67 = 670.
Caught and corrected during our automated verification pass.
How it works
Three steps, zero setup
Pick a chapter
Choose your exam, subject and chapter — or let the adaptive engine choose for you.
Practise the real thing
Actual past questions in exam order, with the timer running if you want it.
See what's weak
Accuracy and time per chapter, so revision goes where it earns marks.
Ability estimate
58%
overall
- Rotational Motion34%
- Thermodynamics58%
- Current Electricity81%
The engine picks the next question from where your accuracy actually sits — harder when you are clearing them, easier when you are not.
Adaptive practice
It moves with you, not through a list
Every answer updates an ability estimate per chapter. The next question is chosen against that estimate, so you spend your time at the edge of what you can do rather than re-solving what you already know.
Per-chapter ability
Not one score — one for every chapter.
Grandmaster mode
Fifteen of the hardest questions we have. One run a day — three a week on Pro, every day on Pro Max.
Spaced revision
Questions you got wrong come back on a schedule.
Full mock tests
Real paper structure, real timing, real analysis.

Adaptive Engine Architecture
How Item Response Theory (IRT) Tunes to Your Skill Edge
Instead of fixed test sets, our algorithm recalibrates your mathematical ability θ after every answer — serving questions where learning efficiency is mathematically highest.
Dynamic Ability Curve (θ vs β)
Per-Chapter Ability Score (θ)
Instead of one blunt total score, EBY AI tracks your exact mathematical proficiency (θ) for every individual chapter independently.
Optimal Skill-Edge Matching
Questions are dynamically picked right at the boundary of what you can solve — preventing boredom from easy questions and frustration from impossible ones.
Spaced Revision & Memory Decay
Chapters where your accuracy stalls or memory decays are automatically surfaced back into your daily practice queue before test day.
