From Baka to Test to Shoukanjuu Nii.http://www.animelyrics.com/anime/bak.../twinsohno.htm
I noticed an untranslated(or rather, it was Romanji-ed but no English translation) line.
As I've mentioned, I'm not a very skilled translator, so between my brother's assistance and Google translate, it seems to break up as "Bright(Azayakana) Transformation(Henshin) Undergone(Togete)". Within the context of the song, especially that section of it, I guess the translation should be "Bright Makeover Undergone". If someone can come up with a better one, please do.
