The official syllabus for Rajasthan JET 2026 is finally here. Not the recycled NEET or JEE Main syllabus some coaching sites have been peddling, but the real outlines released by Swami Keshwanand Rajasthan Agricultural University (SKRAU), Bikaner, in the JET-2026 guidelines booklet. The exam is on 21 June 2026 - seven days from now. That means your study plan needs to be incisive, not exhaustive.
The booklet's Annexure-II gives you subject‑wise broad outlines, and for most subjects, it tells you exactly how many questions come from each unit. This is as close to an official topic‑wise weightage as you will get. Here is the breakdown.
Before diving into the syllabus, lock in the essentials. The exam pattern is fixed and non-negotiable.

Biology has a clear split: Botany (25 questions) and Zoology (15 questions).
The official broad outlines group Mathematics into eight major units. Unlike Agriculture or Chemistry, no per‑unit question count is specified, but expect a roughly even spread, with traditional emphasis on Algebra, Calculus, and Coordinate Geometry.
You have seven days. Divide them by subject, not by unit. Focus on the units where you are weakest, but never skip a unit entirely - even a single question can swing your rank in a tight merit list.
The official syllabus PDF (Annexure‑II) is available in the JET‑2026 guidelines booklet on jetskrau2026.com. Download it now and keep it open on your screen while you revise. Every topic you read in these last hours should trace directly to a line in that document.
