What is life like at IISc Bangalore? I'm curious about undergraduate life, specifically about things other than academics, like social life. Also, what is the male-to-female ratio like?

Life at IISc is different from life at other universities owing to its uniqueness.

The campus of IISc is mesmerizing. The new hostels are pretty good and comfortable. In a mess, one has an option between 4 different types of meals(South Indian veg and non-veg; and North Indian veg and non-veg). Regardless of how good the mess menu is, one is bound to get bored of the taste eventually. But there are many food joints that deliver food just outside the hostels.

Academic life in the institute is quite hectic. Students have to spend a considerable chunk of their time in academics.

In IISc, there are numerous student-run clubs. It includes the major clubs like Dance, Music (Classical and Rock), Theatre and Sports. These clubs also conduct regular workshops and training for interested students. Apart from these clubs, there are plenty of other clubs like Nature club, Vivekananda Circle, Adventure Club, Notebook Drive(these club works for students and teachers from various schools to simplify lessons by incorporating play, models and fun activities), Bird watchers club, Photography club, Yoga club, the list is endless. Students from almost all parts of India study in IISc. Most of the festivals are celebrated by each and everyone irrespective of their background.

Gymkhana offers all sports facilities such as badminton, tennis, volleyball, basketball, swimming, etc.

IISc offers excellent infrastructure and facilities for most departments, and the professors are extremely qualified and experienced in their field. Also, many Nobel Laureates regularly visit to impart their share of knowledge.

IISc organizes an Open Day, which is the only day IISc allows anyone to visit the campus. On this day, IISc students display fascinating experiments, models, and posters. School and college kids can also participate in various quizzes and competitions organized on Open day.

IISc students, with the help of authorities, organize a fest called Pravega. It is similar to fests organized by most colleges. It includes competitions and concerts.

The number of male students is higher for engineering courses. The male-female ratio is higher for core sciences and undergraduate courses.
