I'm throwing a fit here because the problems that have temperature in them throw my calculations off. In K, the temp. gets to be really high and it takes a while to do the math. Is there a quick way around this?

most of the time, they use like 25C or something, which is 298K. So I just round it off to 300K and just remember the answer will be around the number but not exactly. It always works for me, and also remember to use different R values, depending on the units given.

the math in chem problems kill me too. But the best way to do it faster is to round the numbers up when you multiply and divide and practice a lot so you quicken your speed. Believe me on the real thing if you end up with a lot of quantitative type chem problems you need to be quick because a minute and 11 secs per problem is definetly not enough in my opinion.

I would not worry too much about the math involved in the General Chemistry section of the DAT. Most question (not all) have the formula as a solution (ex. (298)(67)/(53)) as a solution, not the actual calculated answer. Also, as far as time constraints, the Natural Sciences section is one of the only sections were there is adequate time. The General Chemistry section will definetely take longer than the others, but fortunately Bio and Org Chem sections can be completed quite quickly. Giving you plenty of time to ponder those tough Gen Chem questions.
