Short answer: Use one main source per subject. If you attend coaching, the modules are usually the main source because the classes follow them. Add standard books for subjects where you need deeper explanations, rather than reading both fully.
If you attend coaching, follow the modules
Coaching modules are designed to match the class schedule, tests and the teacher's approach. Reading them keeps you in step with the course. Switching to a different book for the same topic often means doubling the work without a clear gain.
When a standard book helps
If a module explains a topic in a way that you do not understand, a standard textbook can fill the gap. NCERT and well-known textbooks tend to have slower, fuller explanations. Use them for the specific topic, not for the whole subject.
If you study without coaching
Standard books are the usual main source, since they are available to everyone and widely reviewed. Some students buy used modules as practice material. Check the batch and year before buying, so that the content matches the exam you are preparing for. See what to check in modules and whether to buy modules second hand.
Avoid doubling the workload
- Choose one main source for each subject
- Use the second source only for topics you find unclear
- Keep a single set of notes instead of one for each book
- Track chapters completed so nothing is read twice by accident
Practice material from modules
Modules often contain a good set of practice questions. Use them after you understand the chapter from your main source. Our guide to organising coaching modules shows how to plan the order.
How the balance changes near the exam
In the final months, revision matters more than new reading. Your own short notes, a single set of modules and previous year papers are usually enough. Avoid starting a new book at this stage unless a gap is clear. Mark the chapters you find hard, and revise them from the source that explained them best. Having fewer materials during revision reduces confusion and saves time. After the exam, clean copies of modules and books can be listed for other students.
Buying and selling modules
Used modules can be a good saving if they are complete and in good condition. See second hand books, and once you finish, you can list your modules through selling your books.
Frequently asked questions
Should I read both coaching modules and standard books?
Choose one main source per subject. Use the other only for topics that are unclear in your main source.
Are used coaching modules worth buying?
They can be, if they are complete and match your exam and year. Check the batch and year before you buy.
How do I avoid reading the same chapter twice?
Keep a single chapter checklist and one set of notes, and mark chapters done from each source.
