With 39 percentile in JEE Mains, it's very unlikely to get CSE or IT at Sanjivani College, Kopargaon under the All India quota. You may try for lower-demand branches or go through management quota. Better chances if you improve your score in the next attempt.
With 91.30 percentile in JEE Main under OBC and home state quota, you have a fair chance of getting CSE at OUTR Bhubaneswar. Last year’s cutoff for OBC (home state) was around your range. It’s a close call, so make sure to fill OUTR CSE as a top preference during counselling and also keep backup options like IT or ECE. Monitor the counselling rounds closely for better chances.
Your JEE Main rank is 983171 so you cannot get admission in DY Patil College because their cutoff is below 3 to 4 lakh your rank is very high so it is not possible for any branch in DY Patil College you can try in some private colleges with low cutoff or go for diploma or other course optio
Since you're a non-domicile candidate and you've appeared for both JEE and MHT CET, you should ideally apply for admission to engineering colleges in Maharashtra using your JEE Main score.
As a non-domicile (i.e., not a resident of Maharashtra), you're not eligible for seats reserved under the state quota in MHT CET. However, JEE Main is accepted for admission to the All India Quota seats in Maharashtra engineering colleges, and these seats are specifically meant for candidates from outside the state.
Many top private engineering colleges and a few government-aided institutes in Maharashtra reserve a percentage of their seats for candidates applying through JEE Main under the All India category. So, even if you’ve written MHT CET, your MHT CET score won’t be valid for state quota seats unless you hold domicile. Hence, for you, JEE Main is the right route.
Make sure to apply during the CAP (Centralized Admission Process) rounds and select colleges where All India Quota seats are available.
With your given JEE Mains percentile and rank you can focus on applying to tier two engineering colleges in Maharashtra as well as explore options in the JoSAA counselling rounds You have realistic chances in certain branches and colleges that generally have slightly higher closing ranks
In Maharashtra for tier two engineering colleges you can consider institutes that participate in the MHTCET counselling as well as those that accept JEE Mains scores These include institutions like Bharati Vidyapeeth College of Engineering Pune MIT Academy of Engineering Pune D Y Patil College of Engineering Akurdi PCCOE Pune and AISSMS College of Engineering Pune These colleges often have seats available for Computer Science Chemical Engineering or allied branches You may find it a bit challenging to get into Computer Science in these colleges as the demand is high but Chemical Engineering or related branches may have higher closing ranks giving you a better chance
For JoSAA counselling your OBC rank places you in a zone where NITs and IIITs in core branches may not be accessible in the earlier rounds but you can explore institutes in the northeast and newer NITs where Chemical Engineering or Electronics and Communication Engineering seats may remain open until the last rounds For example NIT Mizoram NIT Nagaland NIT Sikkim NIT Arunachal Pradesh or NIT Puducherry may have closing ranks that match your OBC rank for Chemical or Electronics and Communication Engineering
When it comes to government colleges for Mechanical Engineering you can look at state level government engineering colleges that take JEE Mains score for admission These include Government College of Engineering Amravati Government College of Engineering Karad and Government College of Engineering Chandrapur Your chances are better in Mechanical Engineering as the closing ranks tend to go higher compared to Computer Science and related streams
In JoSAA it is important to fill a wide range of choices and not limit your options only to preferred branches You should include Chemical Engineering Mechanical Engineering Production Engineering Metallurgical and other allied branches to maximize your chance of securing a seat during the counselling process Participate in all rounds and pay attention to mock seat allotments to understand where your chances are higher
Keep documents ready such as your JEE Mains admit card score card category certificate and academic certificates for smooth participation in counselling Also consider applying for state counselling processes such as MHTCET or similar as a backup
With seventy five percentile and an All India Rank of three lakh sixty seven thousand and an OBC rank of one lakh thirty one thousand you can target tier two colleges in Maharashtra like Bharati Vidyapeeth College of Engineering MIT Academy of Engineering D Y Patil College of Engineering and PCCOE for branches like Chemical Engineering or Mechanical Engineering Through JoSAA you may expect chances in Chemical or Electronics and Communication Engineering at newer NITs and institutes in northeast India Be flexible with your choices and participate actively in all counselling rounds to secure a suitable seat in a good college
