Guide to IIT — Everything You Need to Know

How to get into IIT — a practical, step-by-step guide

Everything students need: exams (JEE Main & Advanced), application timeline, popular branches, campus life, scholarships and exam preparation tips.

Start with Admissions

What are the IITs?

The Indian Institutes of Technology (IITs) are a group of autonomous public technical universities in India known for strong engineering programs, research, and alumni success in technology and entrepreneurship.

Key facts

  • Multiple campuses across India (IIT Bombay, Madras, Delhi, Kanpur, Kharagpur, Roorkee, Guwahati, and newer ones).
  • Offer undergraduate, postgraduate and doctoral programs in engineering, sciences, design and management.
  • Highly competitive admissions via JEE (Joint Entrance Examination).

Popular branches

Computer Science, Electrical, Mechanical, Civil, Chemical, Aerospace, Metallurgical, and interdisciplinary programs like Data Science and AI.

Admissions: JEE Main & JEE Advanced

Admissions to the B.Tech programs typically involve two steps: scoring well in JEE Main and then qualifying in JEE Advanced for IIT seats.

Typical timeline (overview)

  1. Year 12 (Class 12) board exams and focused JEE Main preparation.
  2. Appear for JEE Main (usually in multiple sessions) — qualifying score required to sit for JEE Advanced.
  3. Top candidates from JEE Main qualify for JEE Advanced; successful candidates are offered seats via a centralized counselling (JoSAA).

Study strategy

  • Master NCERT for basics, then move to advanced problem-solving with coaching materials or standard books (e.g., H.C. Verma, I.E. Irodov for Physics; R.D. Sharma/Pradeep for Maths practice; O.P. Tandon/Organic texts for Chemistry).
  • Daily problem practice, full-length mock tests, and timed revision cycles.
  • Focus on concepts, application and speed & accuracy.

Application tips

  • Keep scanned copies of required documents (photo, signature, class-12 marksheet) ready.
  • Follow official schedules and portals for registration and admit cards.
  • Use mock tests to simulate exam-day conditions and refine time management.

Campus & Student Life

IITs are known for rigorous academics balanced with a vibrant campus life—clubs, cultural fests, technical festivals, startups, and research labs.

Academic culture

  • Strong emphasis on hands-on projects, lab work and research opportunities.
  • Interdisciplinary collaboration is growing — AI, robotics, climate tech, and biotech are common research areas.

Beyond academics

  • Clubs: coding, robotics, literature, entrepreneurship, photography and more.
  • Festivals: techfests (e.g., Kshitij/Techkriti), cultural fests, sports meets — great for networking and experience.
  • Placements: top IITs have strong placement records in tech companies, finance, consulting and startups; internships are widely available in summers.

Scholarships & Financial Aid

Most IITs have merit-based and need-based scholarships, fee waivers, and student loan guidance. Always check the institute's official student welfare portal for the latest schemes.

Frequently Asked Questions

Q: Which branch should I choose?
A: Choose based on interest and career goals. Computer Science is high-demand, but branches like Electrical, Mechanical and Civil offer strong foundational engineering training and domain-specific careers.
Q: Can I switch branches later?
A: Many IITs allow branch changes after the first year based on CGPA and seat availability, but policies vary across campuses.
Q: Are preparations possible without coaching?
A: Yes. Self-study with the right books, discipline, and regular mock tests can work. Coaching helps many students but is not mandatory.

Practical Tips & Hacks

  • Make a 6-month revision plan before exams with topic-wise time allocation.
  • Maintain a mistake log from mock tests and revisit it weekly.
  • Practice previous years' JEE Main & Advanced papers under timed conditions.
  • Balance sleep and health; short breaks improve concentration.

Resources (starter list)

  • Previous year JEE papers
  • NCERT Class 11–12 books
  • Standard reference books for each subject
  • Official JEE portal & JoSAA counselling site
