[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]You have to take Biology, Chemistry and I forget what else as graduation requirements but if they offer AP yes you can take them directly.  With math you go to the next class and if its an AP you can take it.  [/quote]
Biology is a prerequisite for AP Biology. Chemistry is a prerequisite for AP Chemistry. No, you cannot just skip those classes. [/quote]

But there is not much time to try to take a higher level science class while in HS ( for ex..one at Montgomery College or another college/virtual) if you don't skip the intro classes and some students are more than capable to skipping the intro classes.[/quote]

[b]What is the actual goal going straight to AP classes?[/b] There’s a reason they have prerequisites, how do you know your child is “more than capable” to skip into those classes? You need to be more specific about what grade your child is in and what classes they want to take. Plenty of students take APs in Physics, Chemistry and Biology at their high school while satisfying the prerequisites, usually one can double up in science by taking electives. AP and Dual Enrollment are equivalent, you don’t need to take both. Some students take post AP classes like Multivariable in math through Dual Enrollment or at magnets.

There’s are some online options, but likely they won’t be recognized by the local district.

Silicon Valley High School for introductory classes:

UC Scout for AP classes.

New poster here. Not sure what OP's motivations are, but speaking for myself, the actual goal is to be able to take more advanced STEM classes and/or a greater variety of non-STEM classes. Things like genetics, organic chemistry or art, history, FL, music.

Simply put, the fewer classes are fixed, the more options students have to take what interests them. Pre-requisites eat up the time slots and some students don't need them. Many countries have chemistry and physics in middle school - classes that are very similar to AP physics 1 and honors chemistry.[/quote]

[b]Don’t be ridiculous, middle school classes are nothing like AP Physics 1. Y[/b]ou can’t take genetics and organic chemistry without college level general chemistry and biology, it’s just plain silly. And nope, college level introductory chemistry can’t be substituted with middle (high) school chemistry.

If your goal is to take more varied classes beyond what’s available in a typical high school, consider early college options:

Usually they are more flexible with placement and prerequisites, you can get credit by examination etc. and you can take the classes you listed. You will still need to show you mastered the prerequisites in some way, they won’t take your word that “some students don’t need them”. Also you’ll have a much harder time to skip if the prerequisite has a lab portion.[/quote]

You mean in MCPS? I agree. But we have experience abroad and the middle school classes were in fact very similar to AP Physics 1 and HS honors chemistry in MCPS. Many countries have medicine as an undergraduate degree and their middle school and HS classes reflect that.[/quote]

No they don’t. I also come from a country with medicine as undergraduate degree. You still have to take college physics and chemistry, way above high school and middle school curriculum.

If you actually want good advice clarify what grade the child is in, what classes he took so far, what classes he wants to skip and which they want to join, and what school they are currently attending.[/quote]

I don’t need your advice, thank you very much. The fact is that n many countries students do classes similar to MCPS honors chemistry and AP physics 1 in middle school, organic chemistry and biochemistry in middle school. [/quote]

Which countries? I've seen a European medical college entrance exam (Romania?) that includes some organic chemistry. But middle school is extreme.[/quote]

Here are chemistry questions for entrance exam to medical school given to graduating seniors. I am not an expert but there seems to be quite a bit of organic chemistry here. You can lose about 5 points out of 30 and still get in.
