About Class 11 Maths Notes

Why this site exists

Class 11 is the year mathematics stops being about memorising a method and starts being about understanding why the method works. Most free notes online skip that transition — they post a final answer and leave the reasoning out, which fails the student the moment a question is worded slightly differently.

This site takes the opposite approach. Every note is written against the Punjab Curriculum and Textbook Board (PCTB) 2025 Class 11 Mathematics book, solved step by step, and presented the way a marking key is structured — so practising here trains the exact habits that earn marks in the exam hall.

The site covers all 14 chapters for the nine Punjab BISE boards: Lahore, Gujranwala, Rawalpindi, Faisalabad, Multan, Sahiwal, Sargodha, Bahawalpur and D.G. Khan.

How the notes are built

• ✓ Every step is shown, not just the final answer, so you can see where each formula was applied.
• ✓ The governing formula, identity or theorem is stated beside the step that uses it — the habit that earns method marks.
• ✓ Worked textbook examples are solved in full because boards regularly adapt them into real questions.
• ✓ Content follows the PCTB chapter order, so nothing is out of place when you revise.
• ✓ Explanations mix English with Roman Urdu, because that is how most Punjab students actually study.

Corrections

Mathematics notes are only useful if they are correct. If you spot an error in any solution, report it with the chapter and question number — corrections are made promptly and the page is updated.
