Colleges in Mumbai

In case you intend to change your university and course mode after completing your 1st year, I don't think it is possible. In certain cases, college change within the same university is possible to a large extent but not the mode in which the course is pursued.
You can still check with your college authorities.

No, that's not possible.
Admission is through counseling conducted by DTE Maharashtra based on marks obtained in Maharashtra Common Entrance Test (MHCET) or rank obtained in JEE-Mains.

Hi,In Pune, only 2 colleges are left and good for chemical engineering which are MIT Kothrud and VIT. In Mumbai, there is ICT which is good.

Hello Sumanth,
Firstly let me offer my heartiest congratulations on scoring such handsome marks in your Diploma exam. Yes, you indeed can get admission in IIT Mumbai. But, unfortunately IIT's don't give lateral admission. Your Diploma would be considered as equivalent to class 12th. You will have to appear for and pass with good marks JEE Mains as well as JEE Advanced. That's all. Best wishes to you.
