Getting Real

You have limited time and 40 complex questions to analyze and answer. Sometimes, the best thing to do is take a deep breath and remember some of the essential multiple-choice test taking strategies. You will not be docked for providing a wrong answer. If you had the time to read the question, you have time to make an educated guess. Keep in mind, however, that no credit will given for anything written in the exam booklet.

Circle or underline if it helps. Conversely, looking at the answer choices and then reading the question may work best. Find a style that works for you. Know what a typical multiple-choice question looks like.

Practicing by taking multiple practice exams over the course of the year is the best way to become comfortable and confident with this section of the exam. The majority of questions will include a snippet of code, which you will have to analyze in one way or another. Sometimes you will given an output and have to choose the code segment that produces that output.

Other times, you may be asked to predict what a particular code segment will print out. More complex questions might ask you to change segments of code to perform a specific task, evaluate recursion methods, describe what will happen when a code segment is executed, and analyze code that may have many correct answers.

Take a look at the sample multiple-choice questions offered by the College Board in its AP Computer Science A Course Description to get a feel for the complexity of the questions you might encounter on the exam. Avoid the most common errors. In CS, you will make mistakes. It comes with the territory. However, as long as you are aware of the most common mistakes and errors, you can hopefully avoid them on the free-response section of the exam. The most common errors include:. Write legibly, clearly, and with good programming style.

This means you should aim for clarity in your programming responses. You want your responses to be as easy to grade as possible. Keep in mind the following when writing your programming responses:. This response from a real AP Computer Science test-taker shows what a neat, legible response with good programming style looks like. This response actually earned a score of 9! Do not use specific numbers, strings, or dimensions of arrays in your code. You want to make your program work with any potential number, string, or dimension, not just the one given to you as an example in the question.

This is a common mistake that many AP CS students make. For example, if a question is about a two-dimensional array and it shows you an image of a 3 by 4 array, do not use the numbers 3 and 4 in your code. Remember, do not use specific numbers! Attempt every part of the question. Most AP Computer Science free-response questions will include multiple parts part a, part b, part c, etc. It may surprise you that part a is usually harder than parts b and c.

Each part is graded independently from the previous parts. This means that if you leave part a blank or provide an incorrect answer, you could still get full or partial credit for the other parts! This is a waste of time and you could potentially lose points. Sounds like a no-brainer, right? To avoid this, underline, circle, or star important details when you first read the problem.

Look at the information you underlined or circled. Did you actually answer the question? Always write down some code in your answer. You will be given no credit for simply describing what you would do if you had the time to write out the code this is not an English exam. You could receive some credit, however, for attempting some aspect of the code. You may not know how to write the full code to address the problem, but always write at least some code for the parts you do Partial credit may be given for having the correct loop bounds, attempting to sum values in an array, etc.

Remember that elegance of code does not matter. For you advanced programmers out there, elegant coding does not count on the AP CS exam. Stick to what you know. You could potentially waste time trying to write really simple, efficient code, or even trick yourself in the process. A brute-force approach is best on the exam. Stay within the AP Java subset.

The subset if given to you for a reason. Keep it simple and use the AP Java subset. Follow Java naming conventions. Start names with a lowercase letter and keep names meaningful but not too verbose.

Use your best judgment. Sometimes the question will contain names that you should use in your code. Comments are completely disregarded by AP readers. You will therefore receive no credit for them.

More than a traditional introduction to programming, it is a rigorous, engaging, and approachable course that explores many of the foundational ideas of computing so all students understand how these concepts are transforming the world we live in.
