Wow, you have a lot of chavrusas. If you are going to do Chovos Halevavos with one chavrusa and Chorev with another chavrusa, and one is a teacher and the other is a fellow student, I would recommend doing Chovos Halevavos with the teacher. Although it seems from what you wrote that you already are doing something else with the other chavrusa and Chorev and Chovos Halevavos would be vying for the chavrusa with this teacher. But to reiterate about Chorev, you don’t have to finish the whole thing or even half of it. Think of each piece as a separate sefer.
By the way it would be pretty funny if one of the people giving suggestions here was actually your teacher.
Oh, and I’m going to add uighwisarogh;oaerhg to my lexicon. It’s definitely more intelligible than ontic dualism. Speaking of which, Microsoft Word apparently never took any philosophy classes because it doesn’t know the word ontic. Actually, it’s the Coffee Room spell checker that doesn’t know ontic; Microsoft Word recognized the word but couldn’t think of any synonyms for it. But I’m not surprised – as I discovered last week, Microsoft Word doesn’t think that hacceity is a word.
