We are all consumers of computer science. Whether we hail an Uber ride, play a game, attend a remote class, or post to social media, we are consuming code. If you want to be a producer instead of a consumer, AP Computer Science is the course for you! Computer science teaches computational thinking and the 21st century skills that are essential for the STEM pipeline. Companies want people who can apply programming skills to solve problems. Taking AP Computer Science will give you these skills.


There are two different AP Exams in Computer Science. The AP Computer Science A exam uses the programming language Java. The AP Computer Science Principles exam is not language specific. In addition to traditional questions, there is a performance task where you will develop a computer program and communicate what your code does.


The AP Computer Science Principles exam consists of two sections: There is a traditional multiple-choice section taken in May and a performance task which is completed over the course of the year. On the multiple-choice section, you have 2 hours to answer 70 questions. The performance tasks involve writing a computer program to solve a problem and submitting a digital portfolio of your work. The digital portfolio consists of a video, written responses, and the actual code.


Most people use social media. When it comes to social media like many things computer science related you can be either a consumer or a producer. With a background in computer science, you can be a producer and work at a social media company and write the code that makes social media happen. As such, you can find a huge variety of computer science related social media accounts to follow.


The only way you can really be prepared for the AP Computer Science exam is through practice, practice, practice. You should take full length AP Computer Science practice tests. But how should you practice? First off, write code! Try to write some well documented code every day. The more practice you have in writing and documenting your code, the better understanding you will have. By documenting your code, you are explaining it to others and thus will be better able to communicate your understanding of computer science concepts.


It is much harder to be thorough and concise than to write a lot. There are three written responses and the maximum you can write is 750 words. Assume your reader is educated in computer science and you do not need to explain Computer Science to them. You need to explain and communicate your work, that your program accomplishes the tasks, and that you understand it.


Let us begin chapter-wise important MCQ Computer Science Class 12. We are going to start CBSE class 12 computer science (python chapter-wise MCQs) from chapter 1 Python revision tour Class XI.


Explanation: Silicon is the primary element in computer chips. Silicon is a highly pure element which is now perfect for the massive computer chip industry. It is cost efficent and easy to use.


Explanation: A mouse is a hardware input device that controls a cursor on a computer. With the help of the mouse, you can select, open, and move files, icons, folders, and text on the PC.


Explanation: The central processing unit is located in the system unit. The system unit controls the entire computer. It includes RAM, Processors, Optical drive, Power supply, Fans, Hardware, Peripheral devices, BIOS, etc.


Explanation: An OS is a kind of program that acts as an intermediary for computer hardware and computer user. The purpose of an operating system is to provide a user-friendly and effective environment.


Explanation: The computer clock speed is normally calculated in gigahertz (GHz) or megahertz (MHz). a gigahertz is equal to one billion ticks per second, and a megahertz is equal to one million ticks per second.


Explanation: The full name of RAM is random access memory. It is a hardware device located in a computer that stores data temporarily. Temporary means it only stores data for some time. RAM is also called main memory, primary memory, or system memory.


Explanation: Spread Sheet is the most appropriate for performing numerical and statistical calculation. A spreadsheet is a computer application that is a copy of a paper that calculates a worksheet. It displays several cells that together form a mesh that includes rows and columns, each cell containing alphanumeric text, numeric values, or formulas.


Explanation: The operating system (OS) is a software that acts as an interface between a computer and a user. It is also called system software. OS is the first program to be loaded into a computer. It manages all the operations of the computer.


Explanation: Binary numbers are represented by 0 and 1. The computer only works on binary numbering systems because according to electronics, any signal can either be in the on state or in the off state.


Explanation: A hard disk drive can be directly connected to a PC via a SCSI interface. SCSI is a group of protocols that send the data between computers and external devices in a physical manner.


Explanation: The use of the IC in a computer has reduced the cost of computers. It is an incredibly small electronics chip integrated with a set of electrical circuits and transistors. It is a very small chip.


Explanation: Speaker is a hardware output device that is used for listening to audio by connecting it to a computer and other devices. The computer's sound card produces sound waves from the speaker.


Explanation: Internet explorer is a web browser software on the windows computer. It helps to search for anything in the world through the Internet. It is also known as Microsoft Edge. If you use a Windows computer, this software is already installed on your computer.


Explanation: Ctrl C is a copy command on the computer. It is a very useful command. This command first selects the text, files, and any data that is stored in the computer's hard disk and then copies it. It is a shortcut key on the computer.


With two different tests for the AP computer science course, you want to be sure you are studying for the right one. This article is going to focus on preparing for the principles exam, specifically by taking an AP computer science principles practice exam.


As mentioned above, there are actually two different AP computer science tests. The AP computer science A practice exam focuses more on JAVA and object-oriented programming. We will be focusing on the AP computer science principles exam.


This exam focuses on the fundamental concepts behind computer science, and the course helps prepare those going into college for computer science to get ahead of other classmates. By passing (scoring a three or higher) the exam, you will likely not have to take the intro to computer science class in college.


Unlike other AP exams, the AP computer science exam is broken into five main ideas instead of units to be taught over the course of a school year. Your teacher may teach them in a different order, but you can be certain these five ideas will make an appearance in your class and on the exam:


There are a total of seventy multiple-choice questions on the AP computer science exam. Unlike the other AP tests, there is no free-response questions on this exam. However, you will be asked to develop a computer program of your choice, in your class, for thirty percent of your score.


This part of the exam accounts for seventy percent of your grade, so you should spend the bulk of your studying on this section. However, the computer program still accounts for thirty percent of your score, so be sure that you are using the class time your teacher permits well to score best.


An AP computer science principles practice exam is one of the best ways to study for the actual AP exam. However, to adequately prepare yourself, you need to be sure that you have a CSP practice test, not an AP computer science A practice exam.


While it can be difficult to not only find an AP computer science principles practice exam, it can also be hard to know if the one you are using has topics that are relevant to what will appear on the AP CSP test. The ones we have listed above along with the resources below will help you feel prepared.


As mentioned above, an AP computer science principles practice exam is a great way to study for the exam. Not only will you narrow down the topics that you need to study and be a more efficient studier, but you will also be able to become more efficient on the exam by utilizing practice tests.


The third resource for studying is something that your AP computer science teacher will give you at the end of the course. You will likely receive a study or review guide that you can use to practice and review topics, especially with peers that took the AP class with you.


Is the AP computer science principles exam hard?The AP CSP exam has a pass rate of right around 66%. However, the AP CSP has one of the lowest perfect score rates at a low 12.4%. If you want a perfect score, it is important to study hard and perform well on the computer
