If i will tell you the fact then For B tech General category student IIM is only dream unless u score More then 99+ percentile because of gender diversity,Field Diversity..U will get a call from IIM rohtak,Baby IIMs,new IIMs with this percentile..Even you will get a call from Culcutta also at this percentile..But you need to justify your low score in 12th & B tech..

There are some other good colleges which is enough good then Baby Iims and New iims..Like MDI gurgao,NITIE,IMT gaziabad,NMIMS,SIBM pune...Soo You have to prepare youself for that clges also..
