IIT

Indian Institute of Technology is intellectually demanding and you will need to have a high level of attainment, commitment, and motivation to pursue this program of advanced study and provide research projects with ISRO, DRDO, etc. IITs are globally recognized as premier engineering education and research institutions.
What makes the Indian Institute of Technology different from other institutions is that they pull our focus toward how we can apply what we have studied in the real world. The assignments encourage the technique of brainstorming and there is a free sense of interaction between professors and students on the feasibility of projects.
The salary package of students in top IITs usually ranges from INR 20-30 lakh PA whereas, for other IITs, it is between INR 10-20 lakh per annum. The highest salary package offered by top IITs is mostly INR 1 crore or above whereas, in other IITs, the annual CTC lies between Rs 30-70 lakh.
The reason everyone wants to get IIT is that it provides good placement packages, career safety, and hence, a secure life. After all, IITs have given us trailblazers like Raj Subramaniam, Parag Agarwal, Kashyap Dalal, Sundar Pichai, and many more. On the other hand, not all IIT Engineers get jobs. Some of them go for their own startups.
According to NIRF ranking, IIT Madaras, IIT Kharagpur, IIT Delhi, and IIT Kanpur are the best in terms of placement, infrastructure, academics, etc.
The IITs around India provide a variety of UG, PG, and Ph.D. programs, mostly in the fields of Science, Engineering, and Technology.
Types Of Degree Programmes Offered at IITs:
1- Bachelor of Science (BSc)
2- Master of Science (MSc)
3- Dual Degree (BTech-MTech)
4- Dual Degree (MSc-PhD)
5- Bachelor of Architecture (BArch)
6- Master of Business Administration (MBA)
7- Dual Degree (BS and MS)
8- Master of Design (MDes)
9- Bachelor of Design (BDes)
10- Master of Philosophy (MPhil)
11- Joint MSc-PhD, etc.
Tips to crack the IIT-JEE exam:
1- Know the syllabus and make a study plan.
2- Understand the concept and Clear your doubts regularly.
3- Avoid reading multiple books.
4- Revise regularly.
5- Try to Solve the previous year's papers and give online mock test series.
6- Work smart, not just hard.
7- Whenever you feel low, talk to your friends, parents, or teachers.
8- Get proper sleep, and eat healthly.
9- Be determined and stay positive.
I hope this will help you.

Two of my favorite quotes basically sum up my interpretation of this:
Lionel Mess said once "It took me 18 years to become an overnight star"
Jon Acuff said once "Don't compare someone else's middle to your beginning". Nobody studies less and gets into an Indian Institute of Technology-they've been studying for longer than they even knew they were. Indian Institute of Technology is definitely one of the most difficult exams to crack. If you start from day 1, things would not be so stressful for you and you can crack the exam. If you wait until last month, things get pretty complicated and stressful. So if you start your studying from day 1, you will score well. First of all, understand your syllabus. Secondly, decide on your study material. Then start giving tests both online and offline. Then practice. Practice is a must. If you don't practice, you'll end up forgetting things, and eventually, you won't be able to write in exams. So keep practicing till the last day.

Studying at IITs and NITs is a dream of many students who study for hours to get admission into IITs and NITs. However, there are a few drawbacks as well:
1. There is a very high level of competition within IITs and NITs as every student is an achiever.
2. You will bear the burden of your family and friends' aspirations, as you will be studying at a top engineering college.
3. You may have been perceived as arrogant by non-IIT/NIT peers.
4. You will be subjected to greater academic pressures than other college students.
5. You will also feel pressured to get a good placement also, again due to the tag of being an IITian or NITian. However, you will have plenty of opportunities in life after getting into IITs or NITs, which can overshadow all these drawbacks.

For the following reasons, NITs are not as famous as IITs:
1. Attention: The IITs usually receive lots of media attention and are treated as a symbol of intelligence among the general public. It is common to see JEE toppers as IITians rather than NITs.
2. Global Ranking: Many top IITs, such as IIT Bombay and IIT Delhi, have been ranked in the top 400 universities in the QS world ranking. This further makes IITs more globally recognised than NITs.
3. Government funding: Since IITs are governed by the central government, there is usually equality in funding and support. This ensures better research and curriculum in IITs compared to NITs, which are regulated within the ambit of respective state governments.
4. JEE exam: Since the introduction of JEE, a student needs to qualify for JEE Advanced for IITs, which is the later stage of JEE Mains. The JEE Main rank is sufficient for getting admission to the NITs. As a result, IIT-selected students are portrayed as more intelligent and popular. Furthermore, IITs have better facilities and placements compared to many NITs.

Hello prahalad
IIT- Indian Institute of Technology
NIT- National Institute of Technology
IITs are the no. 1 institutions in India. IITs and NITs are not the same when compared to the level of studies. IITs possess a high grade infrastructure of courses, scope, faculty members as well as top-scoring students versus NITs. On the other hand, NITs do have batches with diligent and smart students, in comparison to the level of top private colleges
When it comes to the quality of education provided IITs are ahead of the NITs. Both IITs and NITs are extremely good in providing education and producing good engineers, but at the same time the top IIT colleges have an edge because of their high standard of studies
All the best. And if it's help you like it.
