I got 93 percentile in mht cet, 93 percentile in JEE main and 72 % in hsc. Can I get a good college for CS/IT in Mumbai or Pune?

With 93 percentile I can guess you have around 120 marks in CET. if you are from general category then you could in Mumbai get the following colleges for CS IT

Ramrao adik Institute of Technology

Saboo Siddique

Datta Meghe

Terna College of Engineering

Thakur College of Engineering

KJ Somaiya Institute of engineering and Information Technology

MIT Pune

KJ Somaiya College of Engineering for information technology course in Institute level seats.

You could also get better colleges like DJ Sanghvi if you feel the institute level forms for this institutes. The cutoff is usually less for Institute level seats as not many people know about them for example if mechanical of KJ Somaiya College of Engineering closes at 140 marks there is a good possibility that the institute level seats for mechanical engineering will close at about 120 marks so I recommend you to fill the institute level forms of all the top institute that you want to get into you as there cutoffs will be below the cap round cutoffs for that Institute.
