Engineering Entrance Exam

Hi Pratiksha,
You have to take entrance exam i.e JEE Mains for this purpose.

No, JEE is required only for engineering colleges across India.

As per me, you can appear for BITSAT 2018. For more details, you can check their website.

Do the hard work and follow NCERT for chemistry, RD SHARMA for Maths and HC Verma for Physics. From these books, you can get decent marks in JEE Mains.

Yes, you have two chances for JEE Advance and three chances for Mains. So you can appear in 2019 Advance exam. But there is one condition on the basis of your 12th board marks, i.e. you should have at least 65% marks (for SC and ST) in 12th boards or be in top twenty percentile of your board.

Just study standard books to keep your concepts clear and only solve the questions you know.

If you want to become a scientist at ISRO, you should appear for the ISRO qualifying exam rather than appear for GATE.
The eligibility:
BE/B.Tech or equivalent qualification in first class with an aggregate minimum of 65% marks or CGPA 6.84/10 (average of all semesters for which results are available). Minimum of 65% marks or CGPA 6.84 in section B alone for candidates with AMIE/Grad IETE qualification.
The qualification prescribed and the benchmark are only the minimum requirement and fulfilling the same does not automatically make candidates eligible for written test.
To answer your question, GATE syllabus for both would be the same.

To get NITs you need to secure above 200 in JEE Mains. I am a student of SC category and I have got 75 marks in JEE Mains but still I couldn't get NIT, Durgapur.

Hello Kuldeep,
No, you cannot. You need to have a M.Sc degree after B.Sc to become eligible for GATE exam.
Only BE/B.Tech graduates are directly eligible for GATE exam.
