Last five years of board papers,
solved the Manim way.
Maharashtra HSC (SYJC) Mathematics & Statistics (Commerce) and Book-Keeping & Accountancy — 10 authentic board papers from March 2022 to July 2025. Every key question steps itself onto the board — write, compute, box, result — with animated LPP graphs, journal-and-ledger renders, narration, quizzes, flashcards and printable solution sheets.
LPP — iso-profit line tours the corners
Constraints chalk in, the feasible triangle sweeps in, then the iso-profit line slides outward — visiting every corner with live z-values — the graphical LPP from March 2025 (Q.6 (A) (ii)).
Regression — the line pivots to fit
Scatter points pop, the centroid drops in, the line pivots around (x̄, ȳ) to slope 2, residuals flash, and the estimate rides the line to y(4) = 7 — March 2023 (Q.6 (B) (i)).
Area under y² = 4x — strip by strip
The parabola grows out of the origin, the region sweeps full, a dx strip rides across, and the integral morphs to A = 8√3 ≈ 13.86 — March 2023 (Q.3 (B) (i)).
Journal entries — every rupee lands twice
The journal draws itself: particulars write on, amounts fly into the Debit and Credit columns while counting, and both sides race to ₹37,950 — March 2024 (Q.2 (A), admission of Reeta).
Ledger — posting & balancing a T-account
A T-account draws itself, gains and losses post on both sides, the ₹12,300 gap becomes the profit transfer, and double rules drop at ₹17,400 — March 2024 (Q.2 (OR)).
Balance sheet — the tally test
Liabilities and assets assemble item by item with counting amounts, then both columns race to ₹6,15,000 and the green banner lands — March 2024 (Q.5 (A)).
Section I: Mathematical Logic to LPP. Section II: Differentiation to Binomial Distribution — every key question solved step by step.

Sources: official board question-paper PDFs (board portal) for 2024–2025 attempts and verified transcriptions for the earlier attempts; the March 2021 HSC exam was cancelled. Maths March 2022 (Commerce) has no public paper — coverage for Maths therefore spans March 2023 → July 2025. Every solution is re-derived and machine-verified before it ships.
