IIT

For M.Sc, there is something called JAM exam.
You can get more information here:
http://jam.iitm.ac.in/jam2016/ac
The candidates who qualify JAM 2016 shall have to fulfil the following eligibility requirement (ER) for admissions in IISc and IITs. All candidates admitted through JAM should have a Bachelor's degree. At least 55% aggregate marks, without rounding off, (taking into account all subjects, including languages and subsidiaries, all years combined) for General/OBC-NCL category candidates and at least 50% aggregate marks, without rounding off, (taking into account all subjects, including languages and subsidiaries, all years combined) for SC/ST and PwD category candidates
in the qualifying degree. For candidates with letter grades/CGPA (instead of a percentage of marks), the equivalence in percentage of marks will be decided by the admitting institute (s).

First, I would like to clarify a misconception among people that Chemical Engineering is more about chemistry. Chemical Engineering has lot of diverse applications in various process industries, oil and gas, renewable energy, pharmaceuticals, polymers etc. Coming to Chemical Engineering at Indian Institute of Technology, Madras (IITM), the department offers several electives which are industrially relevant. The department has facilities such as Sophisticated Analytical Instrumentation Facility (SAIF) and High Performing Computing Environment (HPCE) for conducting research. The department also offers lab courses to students to learn software's such as Aspen Plus, Mathematics, Abacus and MATLAB which is uncommon among other colleges which offer Chemical Engineering because the cost of these packages are very high. The department has various research groups working on Polymer sciences, Biochemical Engineering, Environmental Engineering, Process Control, Renewable Energy, Reaction Engineering and Fluid Mechanics etc. Our process control group is rated among the best in the world. The department offers a unique minor called systems engineering which is the most preferred minor among students from different departments. Students get placed in different core companies such as ITC, HUL, Shell, Reliance, Dr. Reddy's, Sumitomo etc. Student receive offers from non core sectors such as Finance, Consulting, IT etc. A small group of students apply for higher studies and if my memory serves right most of them get admitted to highly ranked universities abroad. I believe this gave you an overall picture about Chemical Engineering at IIT M.
