MHTCET

First of choosing IT department is a great decision Ria. Yes, you'll get admission easily in 1st or second round. I'll suggest you to fill some good colleges above RGIT in preference form like VIT, DJSCOE . They are good colleges than RGIT.

There are no separate reservations in DJ Sanghvi for ladies or OBC or any other thing except for Gujrati Caste Linguistic Minority. Depending on the cut-off, you can get mechanical through the open category. There is no harm in trying. Hope this helps. All the very best.

Hello Pratik,
You scored well in PCM group but as per your CET marks, you can try in cap round and then if it manages, then take admission with management quota. Thank you.

Sorry to be harsh but the answer is no. For getting admission to VIT and that too in CS you will need a very good score in between 160 to 170 in CET for open category. But this is related to last years cutoff and if your luck is with you then you might get admission but the chances of this happening is 23 %. However you can check Last years cutoff list for various college in Maharashtra which is available on http://www.dtemaharashtra.gov.in/ website you can check it and try to fill the option for accordingly. This list is very helpful because most of the time cutoff remains at the similar level. Hope this helps.

Not sure about your CET score but you can get chemical engineering with help of your JEE Mains marks.
You need to wait for 2nd or 3rd CAP round. Hope this will help you. You can ask if you have any queries in comments.

It would be very difficult I guess but it depends on a lot of factor like, average score this year, people applying and then taking admission. A lot of people apply in Thakur for minority quota so it makes it very competitive and difficult.

Sorry to say that PCB scores aren't allowed for engineering all over Maharashtra. Secondly D.J. Sanghvi provides B.E in biomedical engineering. Hope this helps. All the best!

55 is on the lower side. Getting admission for CS and IT is not possible.
You might try your luck with ENTC (second shift).
