Frequently Asked Questions

CDS Exam 2026 - Your Questions Answered

Everything you need to know about CDS preparation and how Vooo AI helps you clear the written exam.

What is the CDS exam pattern 2026?
CDS for IMA, INA and AFA has three papers: English (100 marks, 120 questions, 2 hours), General Knowledge (100 marks, 120 questions, 2 hours) and Elementary Mathematics (100 marks, 100 questions, 2 hours). CDS for OTA has only English and GK papers (200 marks total). Negative marking of one-third applies to all papers. UPSC conducts CDS twice a year — CDS 1 in February and CDS 2 in September.
How is CDS different from NDA?
NDA is for Class 12 pass students aged 16.5 to 19.5 years while CDS is for graduates. NDA Maths is Class 11-12 level while CDS Elementary Maths is Class 10 level — making CDS Maths more accessible. Both are conducted by UPSC twice a year and both lead to being commissioned as an officer in Army, Navy or Air Force. CDS gives a second chance to graduates who missed NDA.
Is CDS Elementary Maths difficult?
CDS Elementary Maths is Class 10 standard covering Arithmetic, Algebra, Geometry and Statistics. It is not difficult conceptually but is challenging due to time pressure (100 questions in 120 minutes — 72 seconds per question). Consistent daily Arithmetic MCQ practice on Vooo AI builds the calculation speed required to score well in CDS Maths within this tight time limit.
Can female candidates appear for CDS?
Female candidates can appear for CDS for the OTA (Officers Training Academy) Chennai only. OTA requires English and GK papers (no Maths). Male candidates can appear for all four academies — IMA, INA, AFA and OTA. After training at OTA, female officers are commissioned into the Indian Army as Short Service Commission officers.
What is the CDS SSB Interview after written exam?
Candidates who clear the CDS written exam are called for SSB (Services Selection Board) Interview — a 5-day personality and leadership assessment. SSB tests Officer Like Qualities, problem-solving ability, communication skills and team leadership. Written exam + SSB + medical examination together determine final CDS merit. Vooo AI helps with the written exam stage — the first hurdle every CDS aspirant must clear.
How many questions should I practice daily for CDS?
For CDS preparation, 40 to 60 MCQs per day split between Maths, English and GK is ideal. Vooo AI free plan gives 30 fresh MCQs daily. Paid plan gives unlimited access — ideal for the final 3 months before CDS where solving 80 to 100 questions daily across all three papers is the recommended target to build required speed and accuracy.
