With a 74.4263582%ile in JEE Mains as an OBC candidate, you'll have a good chance of securing a Computer Science Engineering (CSE) or related branch in various IIITs and other government-funded technical institutions. You might also find opportunities in certain state-run engineering colleges, especially if you have a home state quota.

Here's a breakdown of potential options:

IIITs:

Consider applying to IIITs like IIIT Bhagalpur, IIIT Manipur, or IIIT Ranchi. These institutes offer CSE or related specializations, and your percentile is likely to be competitive for admission, especially with the OBC category.

NITs:

While top NITs with CSE programs might be challenging to get into at this percentile, you could explore NITs with lower cutoff ranks or consider branches like ECE or EEE which might have better chances.

State Government Colleges:

State-run engineering colleges (like GECs in Gujarat, Odisha, or Haryana) can be a good option, especially if you have a home state quota and can utilize it for admission.

Special Rounds (CSAB):

Participate in the Special Round (CSAB) after JoSAA. This round involves filling vacant seats and can be an excellent opportunity to secure a seat in a desired branch or institute.

Private Universities:

Explore private universities like SRM or VIT (which use their own entrance exams like VITEEE). These institutions may offer ECE or related programs based on your JEE Main performance.

Important Considerations:

Category Rank:

Your OBC category rank is crucial. It significantly improves your chances compared to the general category.

Home State Quota:

Many colleges have a home state quota which increases your chances of getting a seat.

Counselling Participation:

Actively participate in JoSAA and CSAB special rounds to maximize your chances of getting a seat.

College Predictors:

Use JEE Main 2025 college predictors to get a better understanding of your admission chances based on your percentile, category, and preferred institutes.

Remember:

Cutoffs vary:

Cutoffs for different branches and institutes change every year based on the difficulty level of the exam, number of candidates, and seat availability.

Consider your preferences:

Don't solely focus on CSE. Explore other related branches like ECE or IT, which might offer better opportunities at your percentile.

Research thoroughly:

Invest time in researching various institutes and programs before making your choices.

By carefully considering these factors and actively participating in the admission process, you can significantly increase your chances of getting into a good engineering college with a CSE or related program.
