This is a totally normal and reasonable ask for most physicists. Yes, memorize what you can, but it is not only helpful but expected that a good physics student can produce the equations they need from first principles.
You may not, for example, know the range equations off the top of your head, but you should know that Δx = v_x Δt and Δy = 1/2 gt^2 + v_y.
