THANK-YOU

AP Physics B:
I often get asked wow it must be really tough to be a teacher...
I am not going to lie, it is.
But, you are the most rewarding part of my professional life and are worth it.
I hope that you got out of the class at least what you put in.

https://secure-media.collegeboard.org/digitalServices/pdf/ap/paragraph-length-response.pdf

The following strategies were developed to help you on exam day:

• Before beginning to solve the free-response questions, it is a good idea to read through all of the questions to determine which ones you feel most prepared to answer. You can then proceed to solve the questions in a sequence that will allow you to perform your best.
• Monitor your time appropriately on the free-response section. You want to ensure that you do not spend too much time on one question that you do not have enough time to at least attempt to answer all of them.
• Show all the steps you took to reach your solution on questions involving calculations. If you do work that you think is incorrect, simply put an "X" through it, instead of spending time erasing it completely.
• Many free-response questions are divided into parts such as a, b, c, and d, with each part calling for a different response. Credit for each part is awarded independently, so you should attempt to solve each part. For example, you may receive no credit for your answer to part a, but still receive full credit for part b, c, or d. If the answer to a later part of a question depends on the answer to an earlier part, you may still be able to receive full credit for the later part, even if that earlier answer is wrong.
• Organize your answers as clearly and neatly as possible. You might want to label your answers according to the sub-part, such as (a), (b), (c), etc. This will assist you in organizing your thoughts, as well as helping to ensure that you answer all the parts of the free-response question.
• You should include the proper units for each number where appropriate. If you keep track of units as you perform your calculations, it can help ensure that you express answers in terms of the proper units. Depending on the exam question, it is often possible to lose points if the units are wrong or are missing from the answer.
• You should not use the "scattershot" or “laundry list” approach: i.e., write a many equations or lists of terms hoping that the correct one will be among them so that you can get partial credit. For exams that ask for TWO or THREE examples or equations, only the first two or three examples will be scored.
• Be sure to clearly and correctly label all graphs and diagrams accordingly. Read the question carefully, as this could include a graph title, x and y axes labels including units, a best fit line, etc.
