THE MADNESS! There must be a better a way! I do not know whether you are doing this already or not, but if you are printing more than 1 page you can print double sided.
If they're printing out that way, something is wrong with the formatting on your end -- are you printing the complete PT, including the title pages, double-sided?
I think I did really well, so I dumped everything in the garbage this morning. I get free printing, so I can just reprint my materials if I actually do need to retake. And I didn't have much use for used tests/practice sets anyway.
After practicing with the various types of games that are on 7sage + printing 10 copies when you don't get a 100% on a game will really strengthen your approach on LGs.
