Hello, my teacher has once said that she gets all of her quizzes from the internet, but I can't find the site. Does anyone have any idea as to where grade 12, hard, biology quizzes may come from? The quizzes are brutal, and it would so great if I could se...

Wow thanks! You are saving my life! And I am Canadian so we don't have AP at the public school, but the course code is SBI 4U1. I tried searching that in google and didn't get anything, but you all have seemed to find me lots. This is greatly appreciated!

I just checked again, all I get is Biology, it doesn't specify if it is General or Molecular (one of the many reasons I love my school :P). Thanks!

When you have final answers, always go back and check them. If the original problem had a constraint as to what the solutions could be, then that is a tip off.

X could be anything except x=1 and 1/3 because that would give you a zero in the denominator. Division by zero is undefined.

A indicates that the two lines must cross at some intersection. B tips you off to parallel lines that have the same slope and can never touch. C means that it is one and the same line.

Prime numbers are numbers that no other factors other than one and themselves.
