If the answer choices on a given question are not particularly close together, using a rule-of-thumb equation rather than the precise equation (i.e. 1.08 CFM ΔT vs. mCp ΔT) can save time.
When putting in your reps on practice questions figure out which of your references is your preferred source for a particular topic (for example, we like the way the MERM describes the Bernoulli Equation, however we like the way the ASHRAE HoF discusses duct heat gain)—make sure to tab your preferred source.
Tab the indices of the MERM and one of the ASHRAE Handbooks alphabetically so that it is easy to jump to a particular section of each index—lookup speed is key!
As you put in your reps on practice questions note the conversions and equations you use most frequently (i.e. converting from volume flow rates to mass flow rates for various fluids at different temperatures; or the amount of water that condenses from a volume flow rate of air, for example)—collate these into a separate section for quick access
Under no circumstances should you be rocking up to the exam with enough references to fill a full-sized checked bag—you will not have enough time or space to manage all of these resources. Do a ton of practice questions and only bring the references you find yourself actually using.
