Most JEE Advanced aspirants never think about architecture until results day. Then they find that three IITs offer a B.Arch, and that taking it needs a separate test held within days. The Architecture Aptitude Test (AAT) is short, pass-or-fail and drawing-based, which makes it very different from anything else in the JEE process. This post explains the official rules and how to prepare in advance, because there is little time once results are out.
Who needs to take AAT?
The JEE (Advanced) 2026 Information Brochure says, in section 24, that the B.Arch programme is available at IIT (BHU) Varanasi, IIT Kharagpur and IIT Roorkee only, and that candidates who want it "will have to PASS the Architecture Aptitude Test (AAT)". Only candidates who qualified in JEE (Advanced) 2026 could take AAT 2026.
The usual Class 12 rule for IIT admission still applies. You must have at least 75% aggregate in Class 12 (65% for SC, ST and PwD candidates), or be in the top 20 percentile of successful candidates in your board, with physics, chemistry and maths as compulsory subjects. Our post on JEE Advanced qualifying marks covers how that cut-off works.
How is AAT conducted and scored?
From section 24 of the brochure:
One paper of three hours, in English only.
Held at all zonal IITs.
Bring your own drawing and colouring aids. There is no separate admit card; you use your printed JEE (Advanced) admit card with original photo ID.
The Joint Implementation Committee sets the pass mark. Candidates above it are declared PASS. "There is no separate ranking in the AAT."
Seats are allotted on category-wise All India Rank in JEE (Advanced), and B.Arch is offered only to those who passed AAT.
So AAT does not change your rank. It only decides whether B.Arch can appear among your choices.
How tight is the AAT timeline?
In 2026 the schedule on the JEE (Advanced) website was: online registration from 10:00 on 1 June to 17:00 on 2 June, the test on 4 June from 9 am to 12 noon (report by 8 am), and results on 7 June, after which qualified candidates could choose B.Arch on the JoSAA portal. That is a two-day registration window and three days between registration closing and the test. Dates change each year, so check the current brochure, but plan on a similarly short gap.
What does the AAT syllabus cover?
The brochure's annexure lists five areas:
Freehand drawing: everyday objects such as furniture or equipment, drawn from memory with correct form, proportion, surface texture and scale.
Geometrical drawing: lines, angles, triangles, polygons and circles; plan (top view) and elevation (front or side view) of solids such as prisms, cones, cylinders and cubes.
Three-dimensional perception: understanding forms with building elements, colour, volume and orientation.
Imagination and aesthetic sensitivity: composition with given elements, creative use of familiar objects, colour grouping.
Architectural awareness: famous buildings in India and abroad, and the architects and designers behind them.
A worked geometrical drawing example
Geometrical drawing rewards a little calculation before you draw.
Problem. Draw the front elevation and plan of a right circular cone standing on its base, with base radius 3 cm and height 4 cm.
Front elevation: an isosceles triangle. Base = diameter = 2 × 3 = 6 cm. Height = 4 cm.
Check the slant edges: each slant side is the hypotenuse of a right triangle with sides 3 cm and 4 cm, so √(3² + 4²) = √25 = 5 cm. Measure each side with your compass; if it is not 5 cm, the apex is misplaced.
Plan: a circle of diameter 6 cm, with a dot at the centre for the apex, drawn directly below the elevation so the two views line up.
A common mistake is to draw the slant side as 4 cm, confusing it with the height. Another is drawing the plan off to one side, so the views no longer project onto each other.
Scale check. For freehand drawing, keep proportions consistent. A 2.4 m dining table drawn at 1:20 should be 240 ÷ 20 = 12 cm long; at 1:50 it would be 4.8 cm.
A preparation routine you can start now
Three sketches a week of everyday objects from memory, then compare with the real object.
One plan-and-elevation exercise a week, varying the solid: cube, prism, cylinder, cone.
One building a week: read about a well-known Indian or international building and sketch it.
Timed practice: a full three-hour mock before JEE (Advanced).
If you are also weighing other architecture routes, see our posts on NATA and JEE Main Paper 2. For the geometry behind 3D views, the Fermi Concept Library covers every concept in mathematics with its own lesson, so you can revise solids and projections one idea at a time.
