Hello,

With a JEE Advanced rank of 3878 in the female category, your chances of getting Electronics and Communication Engineering (ECE) at an IIT depend on the specific IIT and its previous year cutoffs.

Usually, for general female category (also called female-open or female-general), ECE cutoffs in older IITs like Bombay, Delhi, Kanpur, and Madras are quite high, often within the top 2000-3000 ranks.

For your rank around 3878, you might have a chance at newer or mid-tier IITs like IIT Bhubaneswar, IIT Gandhinagar, IIT Hyderabad, IIT Patna, IIT Ropar, or IIT Indore, where the ECE cutoff for female candidates has sometimes gone beyond 3500 or 4000 in recent years.

So, based on past trends, Electronics in top older IITs may be tough, but in newer IITs, you have a reasonable chance.

Hope it helps !
