Thought of something that would make prfs a lil better. If the reviewer, say on the 5th prf, makes a thingy where he takes all the results from the pervius prfs into one, so u can se if you got better or worse at things. (sorry for the crappy english, had a rough day) What ya say? Could help if you ask me. It might just be me being to lazy to read my old prfs.
