Hey Shaik,

First of all the eligibilty crteria of B.Arch states that a candidate should have passed his/her 10+2  examination with 50% marks in Physics,Chemistry and Maths  and also in the aggrete.For admissions to B.Arch courses in different institutes you have to qualify JEE Mains Paper 2.The same applies for NATA entrance examination.Now based upon your JEE Mains percentile NITs, IITS and CFITs will be not possible for you to get admission in because the cutoffs are within the range of 90-95 percentile.You may try for other private colleges.You may have to wait for the second or third round of the cutoffs list.
