Questions related to GATE
I have completed my graduation in 2016 in computer science.now Im working in company and Im writing my gate exam to pursue mtech in artificial intelligence so which college will be good ? what is the process to apply?
Hello,
Best colleges to apply Mtech are:
- IIT Hyderabad( GATE )
- Amrita Vishwa Vidyapeetham, Coimbatore (Entrance Based)
- IIT Ropar (GATE)
- Indraprastha Institute of Information Technology, New Delhi (IPU-CET)
- Defence Institute of Advanced Technology, Pune
- Chennai Institute of Technology
- Woxsen University
- IIIT Lucknow - Indian Institute of Information Technology
- Gautam Buddha University
In order to be eligible for MTech AI, you are required to hold a BE/ BTech degree in Computer Science or Artificial Intelligence from a recognized university.
You must also score a minimum 50% marks or equivalent GPA to be eligible for admission.
- Some colleges or universities select students depending on their marks in the Bachelor’s degree examination.
- However, some colleges also conduct their own entrance exams.
Hope this helps!!!
how many marks should I get to be placed in one of the best nits
Hi.
Since you have not mentioned the name of any NIT or your category or the field *-u are interested. So, I will be telling cutoff range [GATE] for NIT Trichy, OPEN, and few known fields
FOR CSE: 807-643
FOR CHEMICAL ENGINEERING: 712-466
FOR COMMUNICATION SYSTEM: 766-681
Good Luck
I filled Gate application with caste category , say C1, but can I apply for admission cap rounds with another caste C2?
hi,
see gate score would be given as per category wise and you can not change the category once exam would take place and results declare. qualifying score would be different for different category and candidates have to participate in the counselling process on that category only.
hope you may understand.
mam can i get rank 1 in gate in 1 month preparation
It is really hard to crack gate with a month's preparation specially if you are going to start your preparation from scratch. However you shouldn't waste more time now and work really. Go through the syllabus, Practice the problems, go through previous years question papers, join some good series and put all your efforts in this month. There are many students who have been working hard for years to crack gate but don't lose hope. For more info you can visit the following link:
