Greetings of the day

First of all, congrats on successful completion of VITEEE exam. When it comes to your first daughter, with a rank of 20,000 its hard to get a Electrical (EEE) seat in Vellore campus as the cut-off was 15,500 in the year 2016. She can try applying for Electrical branch at Chennai campus where she can easily get a EEE seat in 1st category itself.

Coming to your second daughter, it's really tough to get a CS seat as it has high demand these days. The cut-off trends keep changing every year and it depends on the number of students attempting the exam, difficulty level, number of available seats, etc. With a rank near to 80,000, its not possible to get any seat in Vellore or Chennai campus in any category. Whereas, she can secure a CS seat in their Amravati (AP) and Bhopal campuses in 1st or 2nd fee categories itself as these are recently established.

VIT AP and VIT Bhopal offer many specialisations in CSE branch such as Artificial Intelligence, Cyber security and Digital forensics, Gaming Technology, Health Informatics, Networking and Security, Data Analytics, Robotics, Business Systems. These courses are future ready and have high placement opportunities. You can opt for the one you like from these specialisations.
