I think it is not good institute to prepare for iit jee because the crowd is huge there in kota branch . They are not paying attention to every student properly I can say that from my personal experience . I have studied both in allen and career point and I think career point is far better than allen in almost all fields. Allen also have poor adminstration. They give preference to money than individuals. They have large batch size upto 300 students per batch. Selection rate is also bad. They only show the result of toppers. Average result percentage is very bad.
