AP Calc AB. How is different from BC? - It depends on how the school teaches it for what the exact content in the course entails, but BC is in general harder than AB. At my school district, AB is the equivalent of a Calc I course at a university, while BC is both Calc I and Calc II, but in the same amount of time. Other schools say AB is Calc I and BC is Calc II.
AP Psychology. Is it a lot of work? - It is usually considered one of the easier AP classes, but it does take some time commitment to memorize all the terms and concepts introduced.
AP World History. Is it similar to the amount of APUSH notes/work? - At my school, World History was harder, but most schools are the opposite. They both usually require a good deal of out of class work/studying.
AP Biology. Easier/harder than AP Chem/Physics? - Haven’t taken these AP’s, but I have taken the equivalent classes at a community college. I found Chem a lot easier than Bio because, if you understand the concepts, it requires a lot less memorization than Bio. I barely studied for Chem, but I had to study for Bio.
AP Gov. I heard it was a lot easier than APUSH with less work. Is this true? - Taking it now. So far, it has actually been very easy. All of the concepts are easy to grasp, and while there is some memorization, there is a lot less than APUSH.
AP English Lit. How much poetry is read? - Depends on how the teacher wants to teach it. The teacher at our school dedicates at least half of the year to it, with several poem analyses a week and over the weekend. I think they usually analyze 60-70 poems in total. However, this may be a high number, as our Lit teacher is known as one of the harshest teachers in the school.
Spanish 4. Is it a big jump from Spanish 3? - It definitely was for me. Spanish III was a lot of vocabulary memorization and learning different tenses, with tests every week or two. Spanish IV was reading books, articles, or short stories in Spanish and answering questions made to be like the AP test. The audio listening also went from super slow speaking to normal speed/fairly quick speaking with some annoying background noise thrown in. If my best friend wasn’t a native Spanish speaker and taking the class with me, it would be really tough without a lot of outside studying and review.
Hope this helped (and didn’t scare you away from taking any cool classes).
