Student guide: how to use PCB Spark

Follow one heading at a time. A useful first visit is Learn → Practice → Revise; return to the same heading whenever you need a refresher.

1. Find your lesson

Select a chapter, then tap a heading such as “Electric Field”. Headings are arranged in learning order. “All Chapters” takes you back to the chapter list.

2. Learn the concept

Open Notes and read the Detailed Explanation with its diagrams. Use NCERT Keywords to recognise terms, Formulas for meaning and equations, NEET Points for exam facts, and Common Mistakes to check traps.

3. Answer and learn from feedback

Open MCQs or the Practice tab, choose an answer, and submit it to view feedback where offered. Try Image questions to read a diagram, Real-world for applications, and Challenge for mixed questions. Sign in if a question asks you to before submission.

4. Revise and move on

Open Flashcards or the Revise tab and try recalling the answer before revealing it. Revisit any mistake in Notes, then choose the next heading from the chapter list.

On your phone: swipe the seven-tab row or the activity row sideways to see every option. The Practice and Revise tabs open their full question and flashcard pages.
