Hello Samarth,
Congratulations for the marks scored by you. There are private colleges in Maharashtra which gives the admission on the basis of class 12th board exam without any requirement of the competitive engineering entrance exams like JEE-MAINS, SRMJEE, WBJEE, APEAMCET,etc. The advantage of getting an admission through 12th board marks is we can choose our desired branch. Some Private engineering colleges in Mumbai, Pune are good but few colleges ask donation and the fee structure is somewhat expensive.
Hope this helps. All the best.
