Regarding both B.Sc Computer Science and B.Tech CSE in Mumbai, this is how your opportunities and procedure would appear like with your grades and OBC category status:
Admission of B.Sc Computer Science in Mumbai
Eligibility: Majority of the colleges in Mumbai (including the colleges of Mumbai University) demand that the student has passed Class 12 (Science stream), as one of the subjects Mathematics and Statics (or Computer Science in some cases). One of the requirements is having a minimum aggregate of between 35-50 percent to get admissions. Relaxation in minimum marks usually exists in case of OBC category.
12th at 52% (OBC): You can apply to B.Sc Computer Science in Mumbai as you get the minimum percentage in general as well as OBC.
Colleges: There are a few renowned Mumbai colleges in B.Sc Computer Science: Mithibai College, SIES, Thakur College, Guru Nanak Khalsa, Ramniranjan Jhunjhunwala College, K.C. College and Bhavan College (which expressly gives different fee structures to the OBC students).
Admission Process: The entry is largely merit and based on (Class 12 marks). Entrance scores such as CUET, JEE MAINS, or MHT CET may be taken into account in this particular college, yet the majority of the B.Sc admission is based on the result of class 12.
List of Documents Required: The candidate may be required to prove their domicile and non-creamy layer status in order to avail OBC reservation and fee concession.
Admission to B.Tech Computer Science Engineering (CSE) in Mumbai
Qualification: B.Tech CSE: The qualifications of General Admission in B.Tech CSE provided in Maharashtra are as follows:
OBC must have minimum 45 per cent marks in 12 th standard.
A pass in either JEE Mains or MHT CET (state level examination of engineering entrances).
52% in 12th (OBC): You are eligible to secure B.Tech seat on board marks basis (Maharashtra-OBC candidates).
GS:61 percentile in JEE Mains (OBC):
61 percentile in JEE Mains normally results in a rank of 3,50,000 and above - this will hardly be sufficient to get admission to top government colleges or top colleges in the form of VJTI, SPIT, or KJ Somaiya (B.Tech CSE) with the OBC reservation. They have cutoffs of ~99+ percentile in CSE, although the cutoffs can be lower in tier-2, and privately owned colleges.
B-Tech your percentile may be considered in some uncompetitive branches of government colleges (except core government colleges mostly in outskirts of Mumbai) as well as, some of the privately managed colleges. B.R. Harne College of Engineering, Lokmanaya Tilak College of Engineering, etc. are the examples (considering that the previous year percentile scores were similar).
Also consider MHT CET, provided you did not, this gives a bigger opening to the local state colleges with OBC reservations.
Recommendations
In B.Sc Computer Science: There are strong chances that you can get admission into popular colleges of Mumbai.
In B.Tech CSE: At 61 percentile, it is likely that you cannot join good colleges in Mumbai and aim of getting into a tier-2 college in Mumbai or any other state privately-owned colleges. Comprime colleges such as B.R. Harne, Terna engineering college and some other colleges in outer areas or smaller colleges that were ready to take lower numbers.
Apply to as many colleges as possible: So that your odds of getting in and choosing what you want to do can increase and so that you can find as many options of B.Sc and B.Tech branches as possible where you cross the cut off/ criteria.
Practical Things To Do
