How would you know the vector AB = OB-OA? Rather than OA-OB

Hello sir!
Would I be allowed to use the scalar product to calculate the cosine of the angle in an exam? Or would it be considered studying above my level and lose points? (My country's educational system already covered scalar products and I can use it quite proficiently)
Thank you.
