Computational chemistry is a branch of chemistry that uses computer simulations to assist in solving chemical problems. [1] It uses methods of theoretical chemistry incorporated into computer programs to calculate the structures and properties of molecules , groups of molecules, and solids. [ 2 ]
The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam.
Many high school students found themselves picking up extra resource material, like prep books and online aids, to help them prepare for the SAT Chemistry test. While the test was challenging, there were distinctions between the SAT Chemistry Test and the AP Chemistry exam, which is a more critical-thinking exam that is used not for college ...
Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
The 2014 AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the previous years, with 60 multiple choice questions (now with only four answer choices per question), 3 long free response questions, and 4 short free response questions.
Historically, the AP exam used several programs in its free-response section to test students' knowledge of object-oriented programs without requiring them to develop an entire environment. These programs were called Case Studies. This practice was discontinued as of the 2014–15 school year and replaced with optional labs that teach concepts.
The AP exam uses paper and pencil. (With the exception of year 2020, only Create and Explore were tested. In 2021, only Create and the multiple choice section were tested.) [7] It lasts 180 minutes and includes approximately 76 questions. The exam is composed of two sections: 74 Multiple-Choice Questions
