I am currently doing work on LLPSI: Pars II and found a mistake in the Answer Key that comes with the Teacher's Materials. For Capitulum XLI Pensum A (de generibus verborum), you are supposed to turn the active constructions into passive ones or vice versa.
The last sentence is given in the textbook like this: Magister te laudat, me reprehendit. The correct answer should be Tu a magistro laudaris, ego reprehendor, but the Answer Key says **Ego a magistro laudor, tu reprehenderis.**
...just in case anyone else is working on this.
