Colleges in Karnataka

The faculty at SJC Institute of technology  is very qualified, helpful and knowledgeable, providing quality education and this college faculty is praised by student for providing both theoretical and experimental knowledgeable and many student said that the teaching staff is cooperative and teaches in manner that is very easy to understand but the behaviour of Lab Staff less satisfied and this college are very strict regarding punctuality. 

No, it is no possible to seek admission at IISc for M.Tech without GATE exam.  Indian Institute of Science, Bangalore offers a four year M.Tech in various specialisations including Civil Engineering, Computer Science and Engineering, Chemical Engineering, Mechanical Engineering and others. Admission to all the courses at IISc is completely entrance-based. The aspirants are admitted to M.Tech at IISc based on scores in GATE exam followed by COAP counselling. To know the specific eligibility criteria and whether there are any alternative pathways for admission without GATE, check out the official website.

I think it won't be easy to get additional in Karnataka with 370 score in NEET 

I suggest checking the official website of the National Eligibility cum Entrance Test (NEET) and the Karnataka Examination Authority (KEA) for the latest cutoffs and admission updates or look for some private colleges or try next year with better rank.
