<p>Each school handles it a different way. Some people take more exams by doubling up on some sciences in one year. There are currently(will be 7 in 2015 after Physics B is split into Physics I and Physics II) 6 AP science exams: AP Biology, AP Chemistry, AP Environmental Science, AP Physics B, AP Physics C: Mechanics, and AP Physics C: Electricity and Magnetism. Additionally, most students enter high school having already taken IPS (Introduction to Physical Science) Honors in 8th grade. But some do not, and take Earth-Space Science in 8th grade instead. Many schools also offer additional science electives: Marine Biology, Earth-Space Science, Anatomy & Physiology, and Forensic Science. </p>
<p>At my school, the honors track works like this:</p>
<p>8th Grade:
-IPS Honors</p>
<p>9th Grade:
-Biology Honors (If you get a form signed and some other stuff, you can take AP Biology.)</p>
<p>10th Grade:
-Chemistry Honors (If you get a form signed and some other stuff, you can take AP Biology. Also depending on what math class you are in and if you already took chemistry honors online, you may take additional AP science classes.)</p>
<p>11th Grade:
-Physics Honors or an AP science (Biology Honors and Chemistry Honors are prerequisites, but Physics Honors is not.)</p>
<p>12th Grade:
-Any science elective or an AP science </p>
<p>Depending on your school’s AP science policy, you may not be allowed to take an AP science class freshman or sophomore year at all, or you might have to fill out some paperwork and get a waiver signed. Some people take Physics Honors before AP Physics B, or take AP Physics B before AP Physics C. This is not really necessary, as some people do take AP Physics B, or even C, without any prior Physics Honors class. Some schools may just allow you to skip honors courses for biology or chemistry, and might even prepare you well enough for the AP exam in a single year. If you wanted to take all 6 AP science exams with adequate preparation and don’t mind doubling up on some APs, this could work:</p>
<p>8th Grade:
-IPS Honors</p>
<p>9th Grade:
-Biology Honors</p>
<p>10th Grade:
-Chemistry Honors
-AP Biology</p>
<p>11th Grade:
-AP Chemistry
-AP Physics B (With the new AP Physics curriculum revision, if you want college credit for physics, you might as well skip AP Physics I and AP Physics II altogether. Each is supposed to take one year of class instruction. You could take a year of honors physics, or just go straight to AP Physics C, which is more likely to get you credit than AP Physics B/I & II.)</p>
<p>12th Grade:
-AP Environmental Science
-AP Physics C (prepares you for both AP Physics C exams)</p>
