First place-Physics!

For the average high school student, the science requirements consist of one of the following sequences:

9^th grade- Biology; 10^th grade- Chemistry; 11^th grade-Physics

or

9^th grade-Earth Science; 10^th grade- Biology; 11^th grade- Chemistry; 12^th grade- Physics

The original order was developed because educators thought it was the easiest way to teach science. Each course requires successively more difficult mathematics. Students could learn Biology more easily than Chemistry or Physics.
