How is Allen lucknow? I have heard many negative reviews.

Is there anyone studying in Allen lucknow this year. I am planning to join it next year. Can anyone suggest me how is the coaching. I am planning to take a drop. A friend of mine elder sister is in Allen. She said teachers are really average. Classes are held only 3 to 4 days due to lack of teachers or space. Only infra is good. Can someone who studies there verify it. Please.
