Is vectors on the AQA, Edexcel and OCR A Level Maths exams?
Yes. Vectors is part of the A Level Maths content that every board examines: AQA section J, Edexcel Pure 10, OCR 1.10. It is assessed in AQA Paper 1, and Section A of Papers 2 and 3; Edexcel Paper 1 and Paper 2; OCR A Paper 1, and the pure sections of Papers 2 and 3.
Is vectors Year 12 or Year 13 content?
Both. The AS content, usually taught in Year 12, is: Vectors in two dimensions: column vectors and i, j notation; Magnitude and direction; unit vectors; Adding vectors and multiplying by a scalar; position vectors and distances; Using vectors to solve geometric problems. The full A Level adds: Vectors in three dimensions, using i, j and k; Position vectors and geometric problems in 3D.
Is the scalar product in A Level Maths?
No. The scalar (dot) product and vector equations of lines are in A Level Further Maths, not A Level Maths. A Level Maths needs magnitude, direction, position vectors and geometric problems in 2D and 3D.
