With a rank of 23000, your chances are better with:
* Lower-ranked government colleges: You might be able to secure a seat in some less popular government engineering colleges in Uttar Pradesh, but this heavily depends on the branch you're aiming for (some branches are more competitive than others) and the specific year's cutoff. These colleges might be located further from major cities and may have fewer resources.
* Private engineering colleges: Your rank puts you within reach of many private engineering colleges in Uttar Pradesh. The quality of these colleges varies considerably, so careful research is vital. Look into their faculty, placements, infrastructure, and accreditation. Be prepared to pay higher fees at private institutions.
To know for certain:
You need to consult the previous year's cutoff ranks for various colleges and branches. These cutoffs fluctuate based on the number of applicants, difficulty of the exam, and the number of available seats. Look at the UPSEE official website or websites of individual colleges for this information. Also, consider using UPSEE rank predictors available online (though treat these as estimates).
