What’s the best way to remember kinematics for my physics exam

This is quite an opinonated question because everyone learns and retains information differently. For me personally, I learn best in physics by doing lots and lots and LOTS of practice problems. the more repetition you get with the material the easier it will be for you to tackle problems quickly. The repetitive practice will also stick the equations in your head for a very long time. Hope this helped! I wish you the best of luck on your exam!

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
