SAT Physical Chemistry in American High School

I don't know what your situation is, but personally, I came to the United States at the end of my freshman year of high school, and then my AP Chemistry and AP Physics were both A's when I was junior, and I learned very easily, if you go to school in China and you can usually get 70 or 80 in exams, there is no problem, Americans think they are difficult, mainly because their understanding is very slow, so they can't understand a question for a long time, like you use the sea of questions tactics in China to pile up, It's so familiar with the formula and the like, so you don't have to worry about it.

I didn't take AP Biology, but I borrowed my classmate's book to see, it's not very difficult, it's just that there are a little more words I don't know, and there's nothing wrong with being serious, in fact, the American course is quite strange, like I think the content of chemistry and AP Chemistery is not much worse, but it just adds a lot of reading, so AP is about the same content to dig a little deeper.

In fact, it is very easy for Chinese children to study science in the United States, basically everything they have learned, and physics is a little simpler than Chenistry.

However, many states in the United States have different textbooks, and some public and private textbooks are also different, so I can't tell you what the situation is, but there is generally no problem.

If you don't participate in any sports teams or work in the student union or participate in a lot of clubs, you really have a lot of free time to study in the United States, and you can take more AP if you can, so that you can be more relaxed in college, and there are many things that can be covered.

If you don't want to take all science or something, you can take other AP courses, like the one I took in AP Psycology, which is very interesting.

As for the SAT exam, it's very simple, it's really simple, it's all the things I learned before I came, and I didn't even review it. orz

As a result, the score came out and was still very high, which made my American friend who had been preparing for revision for a long time angry.

PS: Honor is actually different from AP, if you want to earn college credits, you have to take AP, Honor is between AP and Regular, AP has a special AP exam, Honor is not.

All in all, good luck and welcome to graduate in the future to be my younger brother (sister?) ），good luck！

I was almost out of high school and came to the U.S. when I was 9 years old.

I've taken Chemistry Honors and Biology AP, but not Physics Honors.

The teachers at Chemistry Honors are ignorant and incompetent, so they don't learn much at all. Generally speaking, if you take the Honors, you will have no problem taking the SAT II Chemistry exam. You need to take a look at the prep book.

I didn't take this one myself.

Biology AP is very specific, and I learned this well. Last year, I prepared for SAT II Biology after the AP exam, and I didn't have to study it on my own. And there is no essay in SAT II Biology.

I use the barron'S and Princeton Review.

These people are more focused on studying at university. There's a lot of information in itYou can also refer to it when you choose a university in the future.

About SAT II.

Good luck :)

1.You should have a book by Princeton or Baran with a few pages dedicated to these naming conventions.

2.The structure of space depends on the electron pair, we all know the 8-electron stable structure, that is, when the outermost electron reaches 8, the atom reaches stability, but the b element is a special case (must remember!! Its outermost shell is stable with only 6 electrons, so in NH3, N itself has 5 electrons in the outermost shell, and 3H and 3 N's electrons form a polar (polarity is charged) covalent bond (single bond), so the remaining two electrons are lone pairs, because the electrons are also charged, so they cannot be in the same plane as H, so a trigonal pyramid is formed; And b does not produce lone pairs, so b and f can be in the same plane, so it is planar

Therefore, to determine whether it is a planar structure, just look at whether it has lone pairs of electrons, if there is a polyhedral structure, if there is none, it is planar.

3.This depends on the polarity or non-polarity of the molecule, the polarity is the curvilinear structure, such as H2O, SF2, because the electronegativity of different elements is different, the formation of electron pairs may be attracted by electronegative atoms, take water as an example, although H and O form a covalent bond, but the electron pair will still be closer to O, (because O is stronger), so it will cause uneven charge distribution, so that the covalent bond is charged, and the two charged covalent bonds obviously cannot be in the same straight line, so they will form a polyline; And the electronegativity of the same element is the same, and the covalent bond formed between them is non-polar, so it is a linear structure; The above mentioned covalent bonds are single bonds, if the molecule contains a common electron pair, there will be double bond formation, such as CO2 carbon and oxygen double bonds, double bonds can not rotate, so the structure containing double bonds is linear, and there are only a few double bond structures that need to be mastered. CO2、NO2 and so on.,The landlord accumulates it himself.。。
