since no calculators are allowed, how much of the test (other than QR) is calculations? I'm not that good at mental math, so doing some GChem questions take me a long time because of simple multiplying and dividing...
i would say that a good portion of the Gchem is come simple calculations.....like pv/t = pv/t , and converting to molarity and whatnot....but on the test they usually always use simple numbers that can be divided and multiplied out rather easily on paper for "nice" numbers...for the most part i think.
