In part c , a point was earned for the statement that retroviruses have an RNA genome and a point for the function of reverse transcriptase. Sample C Score 10 In part a , a point was earned for the description of the infection phase, a point for the dynamics of the bacterial growth, a point for the survival of resistant bacteria, and a point for dynamic equilibrium.
A point is earned for the synthesis of the viral proteins, and a point for the break down of the cell membrane. In part c , a point was earned for stating that the genetic material of a retro virus is RNA and another for the function of reverse transcriptase.
Sample D Score 6 In part a , a point was earned for exponential growth. In part b , a point was earned for attachment to the host and another for injection of DNA. A point is also earned for the description of lysis. Part c earned a point for RNA being the genetic material of the retrovirus and another for the function of reverse transcriptase.

An early study published in AP: A critical examination of the Advanced Placement program found that students who took AP courses in the sciences but failed the AP exam performed no better in college science courses than students without any AP course at all. Referring to students who complete the course but fail the exam, the head researcher, Phillip M.
Sadler, stated in an interview that "research shows that they don't appear to have learned anything during the year, so there is probably a better course for them". Like Sadler's study, both found that AP students who passed their exam scored highest in other measures of academic achievement. Several states use Advanced Placement data for accountability purposes, and U.
News and World Report use data on Advanced Placement course offerings and participation to rank high schools. This led one researcher to state, "Clearly, offering AP alone will not magically turn a failing school into a successful one. From Wikipedia, the free encyclopedia. American program with college-level classes offered to high school students.
