Comparing the Two AP Computer Science Courses<\/h2>\n\n\n\n
There are two AP Exams students can consider in Computer Science:<\/p>\n\n\n\n
- \n
- AP Computer Science exam A (APCSA)<\/strong> – The AP Computer Science A exam utilizes the programming language Java.<\/li>\n\n\n\n
- AP Computer Science Principles exam (APCSP) <\/strong>– The AP Computer Science Principles exam is not language-specific. <\/li>\n<\/ul>\n\n\n\n

<\/figure>\n\n\n\nEarning college credit by passing the AP Computer Science (APCSA) exam or AP Computer Science Principles Exam isn\u2019t easy – and even if you do pass the exam, there\u2019s no guarantee you\u2019ll be given college credit for your efforts if you score less than a five on the test. According to figures published by the AP College Board<\/a>, in 2022 only 23.9% of students taking the APCSA and only 12.4% of students taking the APCSP scored a five on the test. Possible scores range from one (the lowest) to five (the highest).<\/p>\n\n\n\n
Although a score of three on the exam is considered \u201cpassing\u201d, many colleges and universities won\u2019t grant credit for anything under a five.<\/strong> So, what are the advantages of taking an AP class and passing with a five? Even if your college or university doesn\u2019t grant credit for your AP scores, your GPA can be raised enough by taking an AP course to get you accepted into a university you might otherwise not qualify for. Successfully passing an AP course with a high exam score looks impressive on any university application and is taken into account during course placement. Although credit may not be granted, you may be able to skip some lower-level classes due to your coursework and exam scores.<\/p>\n\n\n\n

Tips for Getting the Most Out of Practice Exams<\/strong><\/h3>\n\n\n\n
Practice tests really help you feel prepared and be prepared for your exams. The feeling of preparation and confidence as you start the exam shouldn\u2019t be discounted. Students who prepare for an exam feel less stressed and more confident – which naturally leads to higher grades. There are several free practice test sites available for both AP Computer Science exams. The best way to utilize a practice exam (multiple-choice, or free-form) is to pay attention to your results as you go along. Frantically re-taking the practice test without a plan of how to improve your understanding of the questions does you no good. <\/p>\n\n\n\n
For all kinds of practice exams, create a paper or online notebook with the questions you answered incorrectly, along with their correct answers. Evaluate why you got the answer incorrect and make a note to yourself about what skills you need to strengthen or what concepts you need to revisit. Take the time to build the skills and knowledge needed by researching and thinking about how to improve. After you feel you\u2019ve revisited skills and concepts, try taking the practice test again. This is a time-consuming process, but reaps the best rewards when it comes to taking the actual exams. This same process works really well for tests outside of the AP exams as well.<\/p>\n\n\n\n
There are many paid test preparation sites which also include practice tests, but this article focuses on free resources. If you are enrolled in an AP class at school, your teacher may have additional resources for you.<\/p>\n\n\n\n
Practice Multiple-Choice Questions<\/strong><\/h3>\n\n\n\n
For the multiple choice questions, you will be given a question and answers A-E to select from. Make sure you understand exactly what the question is asking. Evaluate the question to each answer and narrow down your responses. Eliminate the wrong answers and choose from the remaining answers for the one that best answers the question. <\/p>\n\n\n\n

Practice Free-Response Questions<\/strong><\/h3>\n\n\n\n
For the free-response questions, you will be given a prompt and be expected to write a short program. You will call methods of classes that you have not seen before, so practice identifying the proper parameters to use when calling methods of classes that are provided to you. Pay close attention to the method descriptions and use the correct type and order of parameters when calling methods.<\/p>\n\n\n\n
