B.Arch Eligibility

Hello Suyog,
I'm giving you the current eligibility conditions for B.Arch through NATA exam and JEE Mains paper 2. I hope that there will be no changes in two years.
For NATA exam:
1) All Admissions to architecture degree course shall be subject to passing of National Aptitude Test in Architecture (NATA) conducted by the Council of Architecture
2) Candidates should have a minimum score of 40% in National Aptitude Test in Architecture (NATA) i.e. at least 80/200, for consideration of admission into first year B.Arch.
3) Candidates should have passed 12th standard or equivalent examination with a minimum aggregate of 50% marks with Mathematics and English as subjects of study.
4) 10+3 Diploma (any stream) recognized by Central/ State Governments with 50% aggregate marks.
For JEE Mains paper 2:
For JEE Mains, I think you should have 75% aggregate marks.
JEE Mains is divided into two papers:
Paper 1: For all undergraduate engineering programs and
Paper 2:n For Architecture and Planning programs
As a B.Arch aspirant, you have two modes to get admission in IITs and other institutions:
If you wish to pursue B.Arch in IIT-Kharagpur or IIT-Roorkee, you need to clear Architecture Aptitude Test (AAT). Students who have secured a rank in JEE Advanced are eligible for AAT. The entrance test will be held only at the seven zonal IITs. In a nutshell, to get admission for B.Arch course in these two institutes, one has to clear Paper 1 (B.Arch/B.Planning) of JEE Mains, JEE Advanced and AAT.
For admission to institutes other than IITs, JEE Main Paper 2 (B.Arch/B.Planning) scores are taken into consideration. Students must note that Paper 2 can be attempted in offline i.e. pen and paper mode only.

A candidate must possess 50% marks in aggregate at class 12th or equivalent with mathematics as one of the subjects at class 12th or 10th + 3 years Diploma (any stream) recognized by Central/ State Governments with 50% aggregates marks.
International Baccalaureate Diploma, after completing 10 years of schooling, with not less than 50% marks in aggregate and with mathematics as compulsory subject of examination.
Candidates seeking admission to B.Arch program should have a valid NATA score obtained in National Aptitude Test in Architecture (NATA) conducted by the Council of Architecture.
The admission will be done on merit basis for which the merit list will be prepared based on marks obtained in qualifying examination and NATA test.
