Hello,

So, according to your first question, you want to  know specialization in chemical engineering for M.Tech after completing the B.Tech program. Here are some good specializations for the M.Tech program

  • Process Engineering
  • Petroleum Engineering
  • Biochemical Engineering
  • Pharmaceutical Engineering
  • Process Control and Instrumentation Engineering

Also, for the second one, you want to know some good colleges that allow management quota for admission in private options. Here are some

  • VIT (Vellore Institute of Technology)
  • SRM Institute of Science and Technology
  • Lovely Professional University

I hope it will clear your query!!

Yes, in the GATE exam you can choose any paper/stream, regardless of your B.Tech or graduation branch there is no strict restriction. However,its recommended that should pick a paper in which you can perform well and which is accepted for the M.Tech or PSU roles you’re targeting. For example, a Mechanical Engineering graduate can appear for Computer Science, but admission eligibility for some M.Tech programs or PSU jobs may still require the original degree branch to match. So, while GATE lets you choose freely, your post-exam opportunities will depend on the institute’s or recruiter’s criteria.

Yes for sure if you graduate from ISI with a B.Math degree and clear GATE in Computer Science, you can apply for M.Tech programs in CSE-related fields at IISc and IITs. Most of these institutes accept candidates from any undergraduate discipline as long as they have a valid GATE CS score. However, some specializations or departments may have additional eligibility requirements, like prior coursework in programming, algorithms, or discrete mathematics. Since your B.Math background gives you a strong theoretical foundation, you’ll likely meet the academic criteria, but it’s best to check each IIT/IISc department’s brochure before applying.

Hello,

Yes, you can appear for the GATE, or Graduate Aptitude Test in Engineering. Through this exam you can get admission to prestigious institutions like IITs and N for the M.Tech or Ph.D. program. After this exam you can even open doors for jobs in the public sector.

I hope it will clear your query!!
