Hello frnd , I share my true experiance.i have taken admission in allen kota for jee main preparation.although I have completed my intermediate in village side college in which student only depend upon coaching.but after taking admission in kota , I secured 140 marks in jee main( obc category) all the que are with allen notes and sheet, some que data was also same.i think if any student only solve allen sheet and notes que then they would 100 and 10% got succeded.allen has 5000 faculty.in kota allen has less expensive fee for preparation comparativaly kanpur , varanasi, agaraa, mathura, mp, etc.i suggest everybody to go in allen for medical or iit preparation.
