Hy Bharti !! 

89 marks is a average score in MH CET as the marks scored in MH CET is normally high . Nothing can be said as of now. You have to wait till the merit list is released but there are some chances for you to get a government college in MH CET,  just wait for the merit list and look for another options as well as you never know about the cutoff level. This year the topper has got above 130 marks in MH CET so the cutoff is expected to be raised. Feel free to contact if you have any further queries.

Good luck!!
