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. Colleges care much more about you taking the class in the first place than what you get on your AP test. The fact is, AP scores hold very little weight in the actual decision process. Is a B+ in AP Chem good?Ī B+ in AP Chem is going to be OK for the vast majority of colleges and isn’t something you should be scared about. 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%. 57.5% 15.5%īased on College Board pass rates, AP Physics 1 is more difficult than AP Chemistry. Do colleges accept 3 on AP Chem?Ĭourse Credit and Placement for AP Chemistry Note that all of the private institutions require at least a 4 on the exam to earn credit while all the public institutions except for Georgia Tech will accept a 3. The two sections of the AP Chemistry exam - multiple-choice and free-response - each makes up 50% of a student’s score. Why are AP® Chemistry scores curved? The College Board curves AP® exams every year to account for normal variation in question difficulty and to maintain a degree of standardization.Ī score of 3 or higher is considered a passing grade. Physics 1 has the lowest pass rate of any AP exam (42.1%) along with one of the lowest percentages of students scoring a 5 (just 6.9%). Which AP Exam has the lowest pass rate?ĭespite a reputation as one of the most difficult AP classes, Physics 1 is also one of the most popular-137,229 students took it in 2021. Other gases, such as carbon dioxide or ammonia, have stronger intermolecular forces and consequently greater deviation from ideality. Why oxygen is not an ideal gas?įor gases such as hydrogen, oxygen, nitrogen, helium, or neon, deviations from the ideal gas law are less than 0.1 percent at room temperature and atmospheric pressure. Is NH3 an ideal gas?įor many purposes we can treat ammonia NH3 as an ideal gas at temperatures above its boiling point of -33 degrees celsius. Sometimes, the behaviour of water vapour can approximate the behaviour of an ideal gas. If not, you may find it hard to commit to this class when you also have other difficult classes to manage. If you plan to major in medicine, AP Chemistry is a great way to gain background knowledge for the courses you will take in college. Is a 4 in AP Chem good?ĪP Chemistry students demonstrated solid mastery of Units 4 (Chemical Reactions) and 5 (Kinetics), with ~15% of students earning a perfect score across all questions about these units. Many gases such as nitrogen, oxygen, hydrogen, noble gases, some heavier gases like carbon dioxide and mixtures such as air, can be treated as ideal gases within reasonable tolerances over a considerable parameter range around standard temperature and pressure. Since the particles are attracted to each other, they aren’t colliding with the walls of the container as often as ideal gases with no attractive forces would. Sample Response: The attractive forces between CO2(g) molecules result in a pressure that is lower than that predicted by the ideal gas law. Why does CO2 deviate from ideal gas behavior? Unit 3: Intermolecular Forces and Properties (18-22%).Unit 2: Molecular and Ionic Compound Structure and Properties (7-9%).
