🔄CDS vs NDA vs Agnipath
CDS is for graduates (20-27 years). NDA is for 12th pass (16.5-19.5 years). Agnipath is for 10th/12th pass (17.5-23 years) but as enlisted personnel, not officers.
If you missed NDA during 12th, CDS is your second chance to become a military officer. CDS written exam is easier than NDA (no advanced mathematics), but the SSB interview is the same challenging 5-day assessment.
Key advantage of CDS over NDA: You already have a degree, so training is shorter (18 months IMA vs 3+1 years NDA). Key advantage of NDA over CDS: NDA graduates are considered senior to CDS-entry officers of the same batch and get a free degree during training.
Both NDA and CDS lead to the same officer rank and pay. After a few years of service, there's no practical difference between NDA-entry and CDS-entry officers.

📚Preparation Strategy
1.CDS English paper tests grammar, vocabulary, comprehension, and sentence structure. It's more language-focused than NDA. Practice: sentence correction, synonyms/antonyms, idioms, fill in blanks, reading comprehension, and paragraph ordering. Wren & Martin is the go-to book.
2.General Knowledge is broad — history, geography, science, economics, polity, and current affairs. Focus on NCERT 6-12 for static GK. For current affairs, 6 months of newspaper reading + a monthly magazine is sufficient.
3.Mathematics is 'Elementary' — up to 10th class level. Much easier than NDA math. Don't over-prepare this section. Focus on arithmetic, algebra, trigonometry, geometry, mensuration, and statistics at basic levels.
4.SSB interview preparation is critical — start from Day 1. Read about Officer Like Qualities (OLQs), practice group discussions, develop opinions on national issues, and work on physical fitness. SSB is where most candidates are eliminated.
