NATA or JEE Main Paper 2: Which B.Arch Entrance Exam Do You Actually Need?

Most first-time B.Arch aspirants assume NATA is the one universal architecture entrance exam. It is not. The Council of Architecture requires either NATA or JEE Main Paper 2 for B.Arch admission, not both at once, and which one you actually need depends entirely on which colleges you are targeting. A small handful of IITs sit outside this rule altogether.

Which exam which college needs

NATA: two parts, no penalty for a wrong answer

The official NATA has an offline Drawing and Composition Test (Part A) and a computer-based Aptitude Test (Part B) that combines Mathematics with General Aptitude, together worth 200 marks across 3 hours, with no negative marking anywhere in the exam. NATA 2026 runs in two phases: Phase 1 offers weekly Friday and Saturday sessions from April to June, within which a candidate may attempt up to two times, and Phase 2 is a single weekend in August. A candidate who has already appeared in Phase 1 cannot also sit for Phase 2.

JEE Main Paper 2: objective questions plus a separate drawing paper, and real negative marking

JEE Main Paper 2A (B.Arch) pairs an objective Mathematics and Aptitude Test with a 100-mark offline Drawing Test scored separately, and unlike NATA, every wrong multiple-choice answer costs a full mark. Paper 2B (B.Planning) is fully objective with no drawing component at all, adding a 25-question Planning section on top of the same Mathematics and Aptitude Test content. Both papers run on the same NTA session calendar as JEE Main Paper 1, so if you are already sitting Paper 1 for B.Tech, adding Paper 2 does not mean a separate application cycle.

The IIT path skips both exams entirely

IIT Kharagpur, IIT Roorkee, and IIT (BHU) Varanasi do not use NATA or JEE Main Paper 2 for their B.Arch programmes at all. Admission runs through JEE Advanced, the same exam used for IIT B.Tech seats, followed by the Architecture Aptitude Test for candidates who qualify. AAT does not produce a score or a rank of its own; you either pass or fail it, and passing makes you eligible for a B.Arch seat allocation based on your JEE Advanced rank through JoSAA.

What this means for your prep order

If NITs, IIITs, or SPAs are your only realistic targets, JEE Main Paper 2 alone covers you and NATA prep is optional. If you are also applying to state or private CoA-recognized colleges, you will need a NATA score too, since most of those colleges do not accept JEE Main Paper 2 at all. If an IIT B.Arch seat is the actual goal, your JEE Advanced Mathematics, Physics, and Chemistry preparation matters far more than either drawing exam, since AAT is a pass or fail gate you clear afterward, not a competitive score you build toward.

This site's own mocks for both exams cover only the objectively gradable, self-contained portions: JEE Main Paper 2B covers the full official B.Planning objective structure, and NATA Mathematics covers the Mathematics component of Part B on its own. Both exclude the Drawing Test, since it is hand-drawn and requires human evaluation and cannot be auto-graded, and NATA's General Aptitude component is excluded too, since it mixes visual perception and architectural-awareness content with no clean split from its safely self-authorable reasoning portion. See the engineering exams directory for practice tests across both.
