With a cutoff of 183 as an SC candidate, you have a good chance of getting into some B.Tech Computer Science/IT programs in India. However, securing a spot in a highly ranked or prestigious IIT might be challenging. Focus on engineering colleges that are not top tier, including newer IITs, NITs, and state-level institutions.

Here's a breakdown of your options:

1. Newer IITs:

IIT Ropar, Indore, Hyderabad, Jodhpur: These IITs typically have closing ranks for CSE in the 600-3000 range for the General category. Your SC cutoff will likely allow you to gain admission to these, according to Vedantu.

2. NITs:

NITs: NITs generally have a broader range of cutoff scores compared to IITs. Look into specific NITs (e.g., NIT Trichy, NIT Warangal) and their closing ranks for the SC category.
