Memorization Nightmare?

Do we need to memorize the gas constant, avg's number, speed of light, boltzmann's constant, plank....?

Will everything be in SI units? will hg mm or torr or ft. appear?

Will all the molar masses be included?

I am having lots of trouble doing gas problems w/o a calculator and having to do tonnes of 3x digit multiplication, will all the number on PCAT be easy?

I really don't get how we're suppose to find say ionization energy without the PT, are we suppose to memorize the whole first 25 elements? or will they give us the valence electrons?

thanks! and good luck!

For your math, working in scientific notation and rounding works wonders (for the MCAT, assuming it applies here too).

When needed, constants should be provided. Also, most of the answers are far enough apart from each other that rounding will get you close to one and then you know that's it. Most of the numbers are easy or have an easy shortcut that saves you all that math effort. If it looks like a time-consuming problem, skip it. If you don't get to five questions because you're answering one, even if you get that one right, you lose.

The only real equation that you need to know is PV=nRT. All other equations are derived from it.

I do not think there would be any 3 digit numbers but it is always to be prepared

When I was doing the pearson practice exams, all the information I needed to solve a problem was there (molecular weights, etc), so I assume the format will be the same on the real thing.
