Defence and Uniformed Services After PCM
Students with PCM can apply for NDA after Class 12, and for other entry schemes after graduation, such as CDS and technical entries, as per the rules of each service. The selection includes written exams, SSB interviews and medical tests. Preparation needs physical fitness, communication skills and consistent study. Read official notifications for age limits, vision standards and other requirements. If you are unsure about the armed forces, keep another academic path ready.
Design and Architecture
Architecture requires interest in design, drawing, geometry and visualisation. Design courses such as B.Des look for creativity, problem solving and portfolio skills. Check which entrance exams and portfolios are needed, and practise sketching and design thinking early. Compare colleges by faculty, studios, projects and industry exposure. Our guide on NIFT vs NID vs UCEED gives more details.
B.Sc and Integrated Science Programmes
For students interested in research, a B.Sc or an integrated BS-MS from a good institute can open paths to M.Sc, PhD, teaching and research careers. Look at the quality of laboratories, faculty research, exposure to projects and the scholarships available. Entrance exams and eligibility vary, so check the official websites.
Fees, Scholarships and Budgeting
- Compare the total cost of the entire programme, not only the first-year fee
- Check scholarships by merit, income and category
- Consider hostel and living costs
- Look at education loan terms before borrowing
- Avoid paying large amounts to agents for admission
