I have studied in ALLEN institute for three years. I had a great experience studying there. This institute have the bestest of teachers for all subject. They all are hardworking. They try to give their best to the students. The administration always supports its student in all forms. They give study material to students which is very good from the point of view of preparation of iit or medicals. They give the students daily work sheets and also help them in extra classes. There is always teachers available for the doubt classes.
Apart from this, institute has lots of building each one have canteens in each floor. Where you get eatables in fare price.
Overall its a nice place to study and also a nice institute which guides your future.
