You cannot get admission in CSE in any of the NITs or IIITs ,but it's also based on your category. For open category there are no chances to get into NITs or IIITs. If you are SC or ST category you may get a seat.
Especially by Josaa you will surely not get a seat , sometimes you may get a seat through CSAB special rounds .
You may get seat in least branches.But if you are Home State student of particular NITs or IIITs or GFTIs you may get a seat .
You will surely not get any seat in Josaa rounds . So you need to opt for CSAB special rounds so that you may get seat in some NITs or IIITs or GFTIs for some branches . CSE is not a sure thing but sometimes you will get due to luck. It depends on the number of persons who have more rank than you appearing in CSAB rounds and number of seats left in those colleges in those particular branches .You'll have 3 options now:
Settle for some other engineering college and go ahead with its curriculum.
Settle for some other college and work for both your sem and next JEE prepration.
Join in some long term institutes and prepare well this time and give next JEE.

Under the UGC (Institution of Eminence Deemed to be Universities) Regulations, 2017, BITS Pilani is classified as an Institution of Eminence. BITS Pilani's Work Integrated Learning Programmes (WILP) are a one-of-a-kind set of educational opportunities for working professionals. WILP are an extended version of the BITS Pilani Campuses' programmes and are analogous to the normal programmes in terms of unit/credit requirements and academic rigour. Furthermore, it capitalises on and expands on students' experience in the field through a high degree of integration, resulting in not only knowledge upgradation but also up skilling and increased productivity. Degrees, diplomas, and certificates in science, technology/engineering, management, and humanities and social sciences may be awarded as a result of the programme.
So this is UGC approved and hence you are eligible for GATE exam .

Hello DL Ram, firstly just don't worry about getting confused. It's okay at your age. I am very happy to hear from you that you are interested in joining the Indian Space Research organization. It's the premium agency of India in space exploration. They need expertise in different fields like mechanical, electrical, chemical, aeronautical and many more branches of engineering. They also require experts in many fields of Science like Physics Chemistry Maths etc. I would like to advise you to have a look at the website of ISRO and look for job advertisements. This will give you a peep into the requirements and you can then choose your education. Best wishes to you.

Hello Keshav Kumar, the four designations that you mentioned have different job profiles. But it's not like mathematics where there is a fixed and only single meaning. Across the spectrum, these terms are used loosely many a times. The airport manager is responsible for managing all personnel and operations within the airport. The aviation Manager is responsible for monitoring and ensuring compliance with the regulatory framework. Airport Programme Manager is another loosely defined term. At many airports across the world, the operator employs a programme or project manager when some new activity is undertaken. After completion of this activity, the job is terminated. The aviation Programme Manager, is in charge of planning aviation-related projects, costing, implementation, etc. I am sure that if you google, you may get much more, though confusing, information. Best wishes to you.

Hello,
What happened that you are seeking a change of college in the sixth semester? The situation can arise when we feel suffocated in an institution and desire change. See theoretically it is possible. Just understand the different dynamics working. Your present college will not like to lose you since they may end up losing fees that you pay. The syllabus of your new college may not be compatible with your current syllabus. In view of all this, it's advisable not to break one's head over this issue. My advice is for you to continue in the same college if the situation is not alarming. But then if it's a must seek clarity on the procedure from the admin staff of your college. Best wishes to you.
