Allen is doing a great job in helping wishers to get their dream. Teachers are very cooperative and have grip on subject as well as entrance exam oriented preparation. Problem solving sessions are also helpful. The other staff is also very cooperative in helping not only in studies but also personal issues whatever they can. The cons is that there is crowd of students at coaching as well as in classes so no specific focus on each student until you are a topper in your section. Of course it all depends on your company as well as determination to achieve. They not only teach but also help in getting out of exam burden with cocurricular activities. Overall recommended to join if you are able to control and master yourself.
