Here are some useful tips which may come in handy during your time at the institute. 

Academics: 

It is the most important factor. From the first year itself, you need to maintain a CGPA of 8.5. If you wish to top your class, you need to study regularly. If you do not study on a regular basis make sure to start preparing at least 2-3 weeks prior to examination. Solve previous years’ questions so that you don’t repent later. Interact with sincere seniors. Their experience can be helpful. Make sure to collect previous year’s questions, questions are usually repeated. 

VT or Internships: 

During placement, recruiters ask for internship experiences. Apply for internships preferably in a government institute after completing 1st or 2nd year of your course. You will get the information on the official website. Ask your seniors too. They can also provide useful information. Vocational training is important for core branches. You can do your vocational training in any industry like thermal power plants or steel plants. 

CV:

Try to build a strong CV. You can go for Tedx, it has good international recognition. Participate in big fests and try to win, these look good on a CV. 

Sports: 

The institute does not place much focus on sports. But you should try to participate in games and sports. There are inter hostel, inter-department tournaments, and also fests organized by halls and hostels. 

Seminars: 

Try to attend seminars on the topics that interest you. If you are interested in competitive examinations like GATE, CAT, or others attending seminars organized by coaching institutes will be a big help. 

Hope these tips will help you.

I have listed a few necessary items one needs to pack before coming to IIT Madras.

IIM Bangalore is known for having one of the most beautiful college campuses in India. Few of the splendid amenities are single-room accommodations, almost 24-hour eating points, best sports facilities in any of the IIMs.
The average duration of lecture hours per day in the first year is 6 hours which reduces in the consecutive years depending upon the electives chosen in each term.
Students of IIM Bangalore have a 5-day working week, with quizzes and exams scheduled on weekends as well. Rarely, extra classes are scheduled on weekends in case of mid-week offs. There are more than 25 clubs promoting academics and extracurriculars. There is one club for each specialization in addition to music, dramatics, and sports clubs. These clubs are good for socializing as well as taking a break from academics. There are excellent sports facilities, both indoor and outdoor, like badminton, basketball, volleyball, football, cricket, tennis, pool table, etc. to mention a few.
IIT Bangalore has excellent accommodation facilities that promote harmony between juniors and seniors. Students of the same batch usually are made to stay within the same blocks.

One of my friends shared her hostel experience at KIIT. 

• For girls, there is only one hostel called the Queen's Castle whereas, for boys, there were several hostels named King Palace 1, 2 and so on. 
• First year students were assigned 4-seater sharing rooms. The size of the rooms was average and comprised of all basic amenities like individual beds, tables, chairs, and shared cupboards. 
• The second-year rooms were bigger and triple-occupancy. Moreover, the students have the chance to choose their own roommates. The rooms and roommates allotted in the second year are permanent for the rest of the years. 

Earlier there were no AC rooms but now I have from my friends KIIT hostel rooms are air-conditioned.
