Suggested Course Sequence for Science For On-level Students wanting an Endorsement (other than STEM): 11th 12th Physics, 10th Choice of: Physics, AP 9th Chemistry, or Chemistry Physics 1 (with prior Biology ESS, ES, or CTE or IPC physics), ESS, ES, or CTE Science Credit Science Credit Course* Course* For Struggling Math/Science Students: 10th 11th 12th 9th Integrated Chemistry, Physics, ESS, ES, or CTE Biology Physics and Physics, ESS, ES, Science Course* Chemistry (IPC) or CTE Science Course* For Students wanting a STEM Endorsement: 12th AP Biology, AP 9th 10th 11th Chemistry, AP Physics PAP Biology or PAP Chemistry AP Physics 1 or 1, AP Physics C, ESS, Biology or Chemistry Physics ES, or CTE Science Course* For Advanced and Accelerated Science Students: 10th 11th 12th AP Physics C 9th PAP Chemistry AP Physics 1 and and/or Anatomy & PAP Biology and AP Biology** AP Chemistry** Physiology For students graduating in 2015-2016 on the Recommended or Distinguished High School Plan, MUST take Biology, Chemistry and Physics plus another upper level Science Class. *CTE Science Credit Courses include Anatomy and Physiology (Level 2 Course like Pre-AP), Microbiology with Pathophysiology (1 semester each, taken together), Forensics, and Advanced Plant and Soil Science ESS is Earth, Space Science ES is Environmental Systems **Double enrollment in science classes can begin at any point in the sequence for advanced students. A note about mathematics and science: Many upper division science courses require varying degrees of use of mathematics. For students seeking to get the most out of their science courses, use the following suggested pre- and co- requisites. To enroll in A student should be taking (or have taken) Pre-AP Chemistry Algebra II or higher Physics Pre-AP Algebra II or higher AP Physics 1 Pre-AP Algebra II, any level of Pre-calculus, or higher AP Chemistry Pre-calculus or higher AP Physics C Concurrent or prior enrollment in calculus is mandatory .
