Physics · Boards & Entrance Exams

Physics, brought into focus.

PadhaiLens studies past exam papers — question by question — to show you what actually gets asked, how often, and in what form. Free notes, previous-year questions and preparation strategy built on data, not folklore.

Pick your exam track

One subject done properly beats six done half-heartedly. PadhaiLens starts with physics — the subject students fear most — across three exams.

How the lens works

No predictions, no "guaranteed questions". Pattern expectation, honestly measured.

Collect

Real past papers — every set, every year — not memory-based question banks.

Classify

Each question is tagged to a concept, a mark value and a question form, building a frequency map of the exam.

Focus

Concepts are ranked into tiers, so your revision time flows to what the paper actually rewards.

Where PadhaiLens is going

Now — PhysicsCBSE Class XII track live with notes, PYQs and the tier map.
Next — JEE & NEETEntrance-exam physics tracks, plus the YouTube channel's first lessons.
Then — More subjectsChemistry, mathematics and biology, each built the same way: papers first, notes second.

From the same desk

PadhaiLens grew out of books written on how students actually learn physics.

The Physics Mind

The Physics Mind

The neuroscience of mastering physics — how memory, problem-solving and exam pressure really work, for JEE, NEET and BSc students.
