Class 12 Physics & Chemistry | Secret Roadmap for Boards 2027 | Ashu Sir

Summary

Ashu Ghai presents a 12-week roadmap for completing Class 12 Physics and Chemistry from October through December, leaving January and part of February for revision. The plan is intended for students covering the full syllabus, rather than only prioritising high-weightage chapters.

Core study principles

• Spend more time practising than reading theory:
  • Physics: roughly 30% theory and 70% questions.
  • Physical Chemistry: focus particularly on questions, with around 70% of study time spent on problems.
  • Inorganic Chemistry: place more emphasis on theory.
  • Organic Chemistry: aim for a more balanced split between concepts and practice.
• Break chapters into manageable sections. Divide a large chapter into four or five parts and a smaller chapter into two or three. Treat each section as its own study unit, and practise questions after completing it.
• Keep Physics and Chemistry in rotation. For example, study one subject on Monday, Wednesday and Friday, and the other on Tuesday, Thursday and Saturday—or study both daily. Avoid leaving either subject untouched for more than two days.
• Follow the syllabus in sequence if you are learning it from scratch. Ashu cautions that starting with only high-weightage chapters is more suitable for students who have already covered the syllabus.
• Use study sessions of around two hours for each chapter section, adjusting the number of sections to the chapter’s size.

Physics roadmap

The proposed sequence moves through the syllabus in roughly weekly blocks:

1. Electric Charges and Fields
2. Electrostatic Potential and Capacitance
3. Current Electricity
4. Moving Charges and Magnetism
5. Magnetism and Matter, alongside Electromagnetic Induction
6. Alternating Current and Electromagnetic Waves
7. Ray Optics
8. Wave Optics
9. Dual Nature and Atoms
10. Nuclear Physics and Semiconductor Electronics

The subtitles do not make every week-to-chapter assignment entirely clear, so this is best read as the suggested order rather than a precise timetable for every chapter.

Ashu recommends focusing first on concepts and numerical questions, and postponing derivations until near the end of December. He estimates that the derivations can then be covered in about six to eight hours, followed by revision in January and February. He also notes that some chapters are short and can be completed quickly, while larger chapters such as Ray Optics may need extra time.

Chemistry roadmap

• Work through Chemistry at approximately one chapter per week, using the same chapter-chunking method.
• The proposed order begins with Solutions, Electrochemistry and Chemical Kinetics, followed by Coordination Compounds and the d- and f-block. Students may also begin with Organic Chemistry, but Ashu advises keeping the chosen area moving consistently rather than jumping between unrelated sections.
• Give NCERT a central role by reading and working through the relevant text for each chapter. Ashu says this covers much of the Chemistry preparation, while recommending extra questions where needed.
• Allow extra time for larger Organic Chemistry chapters, such as Alcohols and Aldehydes. Time saved on shorter chapters can be reassigned.
• Use the later part of the plan—ideally week 11, or week 12 if necessary—for Chemistry previous-year questions (PYQs).

Final preparation and revision

• In week 12, complete two mock tests for each subject.
• Analyse each mock test and sample paper rather than merely counting the score. Use errors to identify weak topics and improve accuracy.
• Completing the syllabus by December is intended to leave January and part of February for revision and additional practice.

Ashu also promotes his Batch 3.0 course as a way to follow the same schedule with instruction. Students can use the roadmap independently if they do not enrol.
