Firstly I was ex student of allen career institute kota.i had experience of three yrs.
When I was studying there I found too many advantages.this institute is very corporative.teachers of this institute are vry supportive, motivative, and good behaviour.teaching style is so attractive.too many short trick u will find during study given by faculty.every topic start with starting point whatever u have already know its doesnt matter faculty member start with zero level and then goes to high level bit by bit.
After taking class of one topic extra race( extrsheet) for homework what did u learn in previous class.and next day will discuss each qnd every question if u have doubt anything in your question.and after 1month of class tqking taste( pattern may be jee mains or advance on condition) by institute and providing rank on ur result where u stand all of them and this result also effect on suffling.suffling start after 3month and providing new batch on ur rank.
This institute also provide study material after during admission for each and every topics as well as extra short handbook for maths physics formula also provided by institute.pattern of level of questions in sheets or booklets are easy to high level as well as previous ten yrs iit jee questions also available last page of ur booklet.but now this time fee may be so costly for iit I dont know now but my time was 90k for 2nd yr.
