I was here in intermediate when I prepared for jee advance. The institute has ventilated and spacious rooms. The attendance system is based on card punching. The faculty is awesome here. Most of them are iitians. Namely Anil Gora sir and Hissaria sir for mathematics. They are very dedicated. Allen institute is also good because of the ethical values they impart to the students. Everytime we had a saraswati in the morning before our classes began. Allen also has a record of most number of students in a year. And most number of iit selections.
