Are calculators allowed? Pretty sure I read that they were not, but i just wanted to double check.

Thanks and good luck

No they most certainly are not allowed. You should memorize easy roots like Sqrt[2] and Sqrt[3] and their inverses just for time's sake. That and remember how to do long division (yuck!)

Nope, no calculators. Another thing you might want to memorize is the sins of the five most commonly used angles.

I know it's stupid, but since I've got a bad memory, I found this little trick helpful in memorizing them:

sin(0)=sqrt(0)/2=0
sin(30)=sqrt(1)/2=1/2
sin(45)=sqrt(2)/2=sqrt(2)/2
sin(60)=sqrt(3)/2=sqrt(3)/2
sin(90)=sqrt(4)/2=1

I thought I am having memory depletion, but alas....
