With an 85 percentile in JEE Mains EWS category as a girl candidate, you have a good chance of getting admission to some NITs, government engineering colleges, and IIITs, but likely not the top-ranked ones; you might need to consider lower ranked NITs or other government colleges depending on your branch preference and specific state cutoffs.

An 85 percentile in EWS category might not be sufficient to secure admission to the most prestigious NITs like NIT Trichy or NIT Warangal.

IIITs:

• Analyze the cutoff trends:

Check the previous year's cutoff trends for different NITs, IIITs, and government colleges in your desired branch to see which ones are within your reach.
