AP Chemistry consistently ranks as one of the hardest AP classes. In May 2020, less than 60% of students passed the AP Chemistry exam. But even in the face of serious academic rigor, more than 145,000 students enroll in AP Chemistry each year.
Scores of 3, 4, or 5 are considered “passing” scores on the AP® Chemistry Exam. The College Board describes a 3 as 'qualified,' 4 as 'well qualified,' and a 5 as 'extremely well qualified.
four main unitsCourse at a Glance Pre-AP Chemistry has four main units.
Unit 1: Atomic Structure & Properties. Unit 2: Molecular & Ionic Compound Structure & Properties. Unit 3: IMF & Properties. Unit 4: Chemical Reactions. Unit 5: Kinetics.
No AP exams are scored on a curve, ever. On published exams, cut off scores for each grade varied from year to year based on question difficulty.
United States History, Biology, English Literature, Calculus BC, Physics C, and Chemistry are often named as the hardest AP classes and tests. These classes have large curriculums, tough tests, and conceptually difficult material.
However, our son thinks taking AP bio in junior year makes more sense since AP biology tends to be relatively 'easier' than AP chemistry for most kids and his next year classes are rigorous. AP Chemistry or AP Biology.
Based on College Board pass rates, AP Physics 1 is more difficult than AP Chemistry. That said, AP Chemistry is not far behind — AP Physics 1 has a pass rate of about 52% while AP Chemistry has a pass rate of 56%.
The 9 Units of AP ChemistryMoles and molar mass.Mass spectroscopy of elements.Elemental composition of pure substances.Composition of mixtures.Atomic structure and electron configuration.Photoelectron spectroscopy.Periodic trends.Valence electrons and ionic compounds.
There are no direct organic chemistry questions on the AP Chemistry Exam. Students will not be asked to name organic compounds, identify isomers, or organic reactions. Some questions may use organic compounds in questions about Lewis Structures and bond angles, or for intermolecular forces of attraction comparisons.
The quantum numbers of electrons can be related to the properties of atoms such as ionization energy and the absorption of light. This covers just about everything you'll need to know about quantum numbers and theory for the AP® Chemistry exam.
Topics may include:Moles and molar mass.Mass spectroscopy of elements.Elemental composition of pure substances.Composition of mixtures.Atomic structure and electron configuration.Photoelectron spectroscopy.Periodic trends.Valence electrons and ionic compounds.
