With a BCECE (Bihar Combined Entrance Competitive Examination) rank of 2697 in the General category and 400 in the EWS (Economically Weaker Sections) category, your chances of getting admission to an agriculture college depend on several factors:

1. College and Program : Different agriculture colleges have varying cutoffs based on rank, category, and the specific program. Generally, higher-ranked institutions and more popular programs have lower cutoffs.

2. Previous Year Cutoffs : Historically, the cutoff ranks for agriculture colleges under BCECE vary. For instance, well-known colleges might have higher cutoffs, while others might accept higher ranks.

3. Category Benefits : Your EWS rank of 400 is more competitive compared to your General rank of 2697. Many colleges offer reserved seats or have separate cutoffs for EWS candidates, which might improve your chances of admission.

4. College-Specific Factors : Some colleges might have a higher cutoff for general seats and a lower cutoff for reserved categories like EWS. Check the specific cutoffs for each college you are interested in.

What to Do:

1. Check Official Cutoffs : Look at the official BCECE website or contact the respective agriculture colleges for the previous year's cutoff ranks. This will give you an idea of whether your rank might be sufficient.

2. Consult Admission Offices : Contact the admission offices of the agriculture colleges you're interested in to inquire about your chances based on your rank.

3. Explore All Options : If you don’t meet the cutoffs for some of the top colleges, consider other reputable agriculture colleges that might have more favorable cutoffs for your rank.

In summary, while your EWS rank is relatively competitive and might improve your chances, it's essential to verify specific cutoffs and contact institutions directly for the most accurate and relevant information.
