chemical mass weight help!

[miceheart]

I am wondering how many atom mass weight we need to memorize? is only atom number from 1-20 is ok, or we als need to memorize some of the transition atom mass too. On the PCAT exam, calculator is not allowed as I can recall, so all the calculation need to be hand calculate right?

Any mass you will need is given. No calculators.

I wouldn't worry about memorizing the atomic masses of all the elements, but knowing general periodicity from general chemistry will be helpful!
