Hello !  Well this marks is unfortunately  very low to get top architecture college . 

The chances is very low . I am also studying  in lko and i know the rank and reviews of colleges . 

But still you can try for private  colleges  in lucknow  here i am giving some of them like 

Axis arch institute ,

Amity school  of  architecture  ,

 Babu banarasi das university  ,

ITM institute  of architecture   etc 

These are the good  private colleges as per my knowledge  where you can approach  . 

Thankyou!
