points for rocket record

would it make sense to change how you get points under "testing" in a lesson? The way it is, you could listen over and over again and each time get more points. For "Know IT", it wouldnt make a difference, but for"Write It" and "Hear It" it would. I'd say there should be more points given if you can listen just once and figure it out and a point less for every time you replay it. It might be a better incentive that way to listen closely and carefully!! But maybe thats too complicated...?
