Engineering

Hello! Maybe it was due to your past academic and MBA entrance exam scores they decided not to waitlist you. Hope you get a much better college! Good luck!

Hello,
Yes, you can take a gap of, say, a year to prepare for the various MBA entrance exams. Though it is also strongly advised to utilize this gap year productively since these exams do not require an entire year to prepare at all. Good luck.

Computer Science Engineering is a course, which is designed to give you the knowledge of Computers and Technology. Computer Programming is a computer language (eg python, Java, C+ etc. ). You can say, computer programming is the syllabus part of computer Science engineering. Hope this helps.
Good Luck.

EWS category is new one this year. So, it is very hard to calculate the rank range of it. IIIT Allahabad is one of the best college in IIIT. Better to go for colleges like IIITDM Kurnool, IIITDM Kancheepuram, IIIT Bhopal, IIIT Ranchi, IIIT Delhi, IIIT Jabalpur, etc. Even getting CSE in JoSAA at this rank will be tough, more chances in CSAB.

Yes, it is a better choice, if you are not able to get a seat in NITs or some deemed universities. CSE is also a good branch with more opportunities. All the best.
