Learning Objective: The student can create representations and models to describe immune responses.
Remember to allocate your time carefully, because the grid-ins will take more time to complete.
To aim for a 5, spend about 45 to 50 seconds per question and answer 60 or more questions correctly.
Advanced Placement Biology (AP Biology or AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States.
For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
In addition to the standard biology topics above, students are required to be familiar with a set of 12 specific biology labs, as well as general lab procedure.
Students are allowed to use a four-function, scientific, or graphing calculator.Learning Objective: The student is able to use calculated surface area-to-volume ratios to predict which cell(s) might eliminate wastes or procure nutrients faster by diffusion.Essential Knowledge: DNA, and in some cases RNA, is the primary source of heritable information.Each question is drawn from a coordinate shown below.This change to the exam shows a growing need for reasoning skills and an inquiry-based learning of essential concepts rather than simple factual recall.In the short free response, there are three 3-point and three 4-point questions. A simple four-function calculator (with square root) is allowed on the entire exam, a change made in 2013. Students will also be supplied with a formula sheet (see below sample questions); this is also a change made in 2013.Since the changes made for the May 2013 exam, scoring a 5 on the exam is much more difficult.(Along the same idea, scoring a 1 is also significantly more difficult! Essential Knowledge: Organisms must exchange matter with the environment to grow, reproduce, and maintain organization.Science Practice: The student can apply mathematical routines to quantities that describe natural phenomena.Note that since the changes in May 2013, there are now 4 instead of 5 answer choices for the multiple-choice questions.This change saves students’ valuable time without altering the rigor of the exam in any way.
