Algebra — JEE Questions, Notes & Weightage
Class 12 Vectors & 3D Geometry NEET weightage: High 76 questions
Covers vector operations, dot and cross products, scalar triple product, and projections. Dot/cross-product numericals (finding angle between vectors, area of a triangle/parallelogram) are tested constantly and feed directly into 3D Geometry.

What is the most common question type?
Finding the angle between two vectors, or the area of a triangle/parallelogram using the cross product, is the chapter's most frequently repeated question format.
Why does this chapter matter for what comes next?
Three Dimensional Geometry (the next chapter) is essentially Vector Algebra applied to lines and planes — the dot/cross-product fluency built here is used immediately afterward.
