How to Use CDS Books Effectively
Simply buying several books will not guarantee success. Follow a structured approach:
Learn → Practise → Test → Analyse → Revise
For example:
English:
Grammar + Vocabulary → Practice Questions → PYQs → Mock Tests → Revision
GK:
NCERT/Standard Books → Current Affairs → Notes → PYQs → Mock Tests
Mathematics:
Concepts → Formula Revision → Topic-wise Practice → PYQs → Timed Tests
Avoid using multiple books for the same topic. One good standard book + PYQs + mock tests + regular revision is generally more effective than collecting too many study materials.
