30 JEE physics problems. Every step drawn.

We gave JEE Saarthi, the JEE track of the ShunyaSaarthi learning platform, 30 JEE Main and Advanced-style physics problems we'd already solved by hand. It solved each one without seeing an answer key, then explained the method and drew the solution one step at a time, the way a teacher works it out on the board.

How it works

What happens when a student asks JEE Saarthi a question

One API call, five stages. Each stage has one job, and code checks the model's work wherever a mistake could reach a student.

  1. 1

    Solve without the key

    The solver works the problem from scratch and is never shown an official answer, so it can't just copy one.

    If a key is provided, a separate step compares the two afterwards. In earlier testing it flagged a wrong key instead of accepting it.

  2. 2

    Check the sources

    An evidence step ranks supporting material from NCERT Class XI, NCERT Class XII, HC Verma and Irodov.

    It only uses material an expert has approved. If none is approved, it uses nothing rather than guessing.

  3. 3

    Teach the method

    The solution becomes a lesson: concepts, prerequisites, how to recognise the problem type, worked steps with equations, common traps and final checks.

    Concept and formula IDs come only from ShunyaSaarthi's NCERT chapter records and are never made up.

  4. 4

    Draw it step by step

    A second model reads the finished solution and draws one diagram per step. The current step is highlighted in each frame.

    Code checks every diagram before a student sees it: it must be valid SVG that scales cleanly, with no scripts or unsafe content.

  5. 5

    Keep what works

    If the lesson or the diagrams fail, the student still gets the correct answer, and the failure is logged rather than hidden.

All 30 problems

Open any problem to step through its solution

21 Main-level and 9 Advanced-level problems covering kinematics, rotation, thermodynamics, waves, electrostatics, circuits, induction, optics and atoms. Answers are shown next to the ones we worked out by hand.

The platform

Where JEE Saarthi fits in ShunyaSaarthi

ShunyaSaarthi is an AI tutoring platform built on the CBSE and NCERT curriculum. JEE Saarthi runs on the same knowledge base, tutor and safeguards as the rest of the platform.

Curriculum knowledge base

Chapter-by-chapter NCERT knowledge for Physics XI and XII, Class X Science and Maths, and more subjects. Search matches both meaning and exact wording.

Adaptive Socratic tutor

Finds a student's level (Beginner to Expert), builds a learning plan, and teaches by asking questions. It adjusts as the student answers, with a short check-in assessment mid-session.

Assessments and papers

Generates questions at the right cognitive level and assembles full exam papers. Every generated question needs a teacher's approval and an NCERT reference.

Teachers stay in charge

Teachers can adjust mastery scores with a written reason (the student's own record is kept), review contributed material, and use teacher-only exemplar papers.

Visual tutoring

A library of ready-made diagram templates for Physics XII, plus step-by-step diagrams drawn for problems the library doesn't cover.

JEE Saarthi

Diagnostic tests, learning plans, practice sessions, mock tests and analytics for JEE, plus the step-by-step solver shown here.

What this test does and doesn't show

Honest limits

This is a field test, not a benchmark. Here's where it stops.

Our problems, not past papers

The 30 problems are JEE-style questions our team wrote and solved by hand before the run. Official past papers with published answer keys are next.

No source material was used

HC Verma and Irodov material is still awaiting expert approval, and the evidence step won't use anything unapproved. It added no source passages here, so these answers come from the solver's own reasoning.

Diagrams aren't expert-reviewed yet

Code checks that every diagram is safe and well-formed, and we checked every answer. No physics expert has yet reviewed every arrow in all 87 frames, and earlier runs caught arrows pointing the wrong way.

Two problems needed a retry

Both Young's double-slit problems stalled while drawing on the first attempt and worked on the second. A time limit on that stage is the fix. Some answers also came back without units, though the numbers were right.
