Hello

The student to faculty ratio varies by institutions, but some of the approximate ratios are:-

Top-tier institutions (like IITs or IISc in India): The student-to-faculty ratio is usually around 10:1 or better, especially in core departments like CSE or ECE

NITs have typically ratios between 15:1 to 20:1

Private engineering college have higher ratio then both that can be 20:1 +
