The Indian Institute of Science, Bangalore, is the world's top research university as per the citations per faculty indicator, while the Indian Institute of Technology, Guwahati, is ranked 41st in the category, according to the coveted QS World University Rankings released on Wednesday.

In the overall rankings, three Indian institutions have figured in the top 200 universities of the world list.
According to the 18th edition of the rankings, the India Institute of Technology (IIT), Bombay, is India's top ranked institution for the fourth consecutive year at the QS World University Rankings 2022.

IIT, Delhi, has become India's second-best university, having risen from the 193rd rank to 185 since last year. It has done so by overtaking the IISc which bagged the 186th rank, a notch below last year's rank, according to the rankings.

No Indian university ranks among the top 250 in the faculty/student ratio category.
Indian universities have made consistent progress in QSs academic reputation metric with 20 of India's 35 entrants improving their scores, while only nine have experienced drops in their rank.
