School learning.
Entrance preparation.
One coordinated plan.

For students completing Class 10, NDA Foundation creates time to strengthen Mathematics, English and general awareness while continuing Classes 11 and 12. Board learning and entrance preparation can support each other through a clear, sustainable timetable.

ACADEMIC FOUNDATIONS

Understand deeply.

Clear explanations, guided questions, independent practice and feedback across school-linked NDA topics.

CONSISTENT PRACTICE

Review every step.

Weekly targets, Saturday tests, timed papers and an error notebook to turn mistakes into progress.

PERSONAL DEVELOPMENT

Grow with purpose.

English communication, teamwork, responsibility and suitable physical activity alongside study and rest.

Know your starting point

Foundation admission
and NDA eligibility.

Joining coaching after Class 10 prepares a student for a future eligible attempt. It does not make a Class 11 student eligible to sit the NDA examination.

General planning band: approximately 16½–19½ years at course commencement. Always use the inclusive DOB window in the relevant UPSC notice, not age on examination day. Eligible unmarried male and female candidates must also satisfy nationality, documentary and medical conditions. This page does not treat projected 2027 DOB ranges as confirmed.

Physics, Chemistry and Mathematics keep the Air Force, Naval and Naval Academy academic routes open, subject to official conditions. Army Wing accepts Class 12 from any stream, but the NDA Mathematics paper remains compulsory.

A sustainable two-year journey

Start early.
Build steadily.

After Class 10 · Set your direction.

Choose the appropriate stream, assess Mathematics and English fundamentals, discuss schooling and boarding, and begin daily reading and suitable exercise.

Class 11 · Build the foundation.

Start algebra, trigonometry, mechanics and English. Use weekly targets, chapter tests and an error notebook, then consolidate through mixed questions and GK revision.

Class 12 · Connect and complete.

Complete board-linked topics, calculus and systematic GAT coverage. Introduce timed papers and review eligibility for the appropriate attempt.

Final phase · Revise with balance.

Balance board examinations, practicals and written-answer practice with full NDA papers. Review accuracy and time, check documents and apply within official dates.

A student starting Class 11 in 2027 may need an examination attempt later than 2027. Plan from actual academic stage and date of birth, with enough time for sleep, meals, exercise and recovery.

Beyond the written examination

Express clearly.
Listen thoughtfully.
Be yourself.

SSB preparation starts with understanding the process and developing genuine communication, cooperation and awareness.

Discuss current communication and personal-interview mentoring with Divya Ma’am and the team. Confirm the practical facilities and support available before enrolment.

Stage I · Screening

Officer Intelligence Rating and Picture Perception and Description Test.

Stage II · Assessment

Psychological tests, GTO tasks, interview and conference. Understand TAT, WAT, SRT and self-description formats while discussing personal experiences honestly.

No mentor can guarantee recommendation. Avoid memorised stories and artificial personality claims.

Study with structure. Grow with support.

Schooling, boarding
and daily development.

CLASS 11 & 12

Schooling clarity.

Confirm the school’s name, board affiliation, subjects, attendance, practical examinations and board-registration arrangements in writing.

GIRLS & BOYS

Residential support.

Separate hostel arrangements, shared rooms, meals, drinking water and cleaning. Inspect accommodation and discuss supervision, laundry and parent communication.

PT & SPORTS

Healthy routines.

Age-appropriate conditioning, stretching and team activities support consistency. Build fitness gradually around health needs, hydration, rest and recovery.

General physical training does not replace official medical assessment. Service-specific medical standards govern selection.

Interview-based academy admission

Super-40.
A purposeful beginning.

A planned capacity of 40 learners, with limited seats and programme availability to be confirmed. The academy interview helps identify preparation needs and readiness for a structured day or residential programme.

Request your interview ↗

Before admission

Request the current written fee schedule, schooling arrangements, hostel availability, materials, assessment plan and communication arrangements. Confirm payment and refund terms and visit the campus.

Academy screening is separate from UPSC and SSB selection.

Parents’ questions

Plan with clarity.

Can I join NDA Foundation after Class 10?

Yes. Enquire about Foundation coaching with Class 11–12 schooling arrangements. UPSC examination eligibility is assessed separately.

Can Class 11 students appear for NDA?

No. Eligible Class 12 appearing or passed candidates may apply under the relevant UPSC notice.

Which stream keeps all NDA wings open?

Physics, Chemistry and Mathematics support Air Force, Naval and Naval Academy academic requirements. Mathematics remains compulsory in the NDA written examination even for Army aspirants.

Can girls join NDA Foundation?

Yes. Girls can enquire about Foundation preparation and separate residential arrangements. Official NDA application depends on notified female vacancies, education, DOB and medical conditions.

What is the confirmed 2027 DOB range?

Use the respective NDA I or NDA II 2027 UPSC notice. No projected birth-date window is presented here as confirmed.

Can I prepare for boards and NDA together?

Yes. A coordinated plan links school Mathematics and science with NDA topics while reserving time for practicals, written board answers, English, humanities and timed papers.

Is boarding available?

Discuss current boys’ and girls’ hostel availability, supervision, meals and study arrangements during your visit.

Does Foundation admission guarantee selection?

No. Selection depends on written performance, SSB recommendation, medical fitness, final merit and notified vacancies.

Where is the academy?

Opposite RIMC Gate, Nimbuwala, Shaheed Kashmir Singh Road, Garhi Cantt Main Road, Dehradun – 248001.

What should parents confirm before paying?
