NTA will release the JEE Main B.Arch Syllabus 2027 on jeemain.nta.nic.in. The Paper 2A syllabus consists of three sections, including Mathematics, Aptitude, and Drawing.
- In the Mathematics section, Calculus and Coordinate Geometry alone account for nearly 45% wightage. These two chapters can make or break your Mathematics score.
- The Aptitude section carries 50% of the total marks, i.e., 200 out of 400. Whereas drawing and mathematics holds 30% and 20% respectively.
- More than 60% of Aptitude questions are from just four areas: 3D Perception, Mental Ability, Analytical Reasoning, and Architecture GK.
Solving previous year JEE Main question papers helps students improve their accuracy by 18-22% in Maths and Aptitude combined, as question patterns repeat heavily.
This article covers the complete JEE Main B.Arch 2027 syllabus with topic-wise breakdown, chapter-wise weightage, do-or-die chapters, topper strategies for all three sections, and a free syllabus DF.

Drawing Test – Important Dos and Don’ts:
- Do practise every day for 30–45 minutes without fail.
- Do use pencils: HB for outlines, 2B/4B for shading; use colour pencils for colouring sections.
- Work on speed, each drawing question must be completed within 20–25 minutes.
- Do include background elements (sky, ground, trees, shadows) to make scenes look complete.
- Do not use a ruler or compass unless specifically asked; freehand drawing is preferred.
- Do not leave the drawing test unattempted; even a rough attempt earns partial marks.
- Do not spend more than 25 minutes on one drawing – time management is critical.
