Hmm...Between Math 140 and Physics 112. Well, I am expressing my bias here, but I definitely recommend going for Math 140. Mind you, I suspect the course will be more computational than theoretical (i.e. more like a calculus for physicists than how Gravitation presented more theoretical concepts on differential geometry).
Physics 112 is stats. If you like stats, then you will enjoy Thermodynamics. I hated studying Thermo and I hate Stats a little more. (Thank, God. Stats or Probability is not on the Basics exam ~ Berkeley's Math Department Prelim.)
