3 classes
A school has 18 classes with 35 students in each class. In order to reduce class size to 30, how many new classes must be formed?
There is an excess of 18 x 5 ie 90 so there has to be an extra 3 classes.
You would first multiply 35 x 18 to find out how many total students there are, which is 630. Then, you would divide 630/30, since you can only have 30 students maximum in a class. This gives you the answer of 21 classes must be formed.
You should probably take classes that relate to your desired career, if any are offered at your high school. General classes to take are English and Math, and other college-preparatory classes. In the end though, the classes that you choose in high school generally won't matter as much to a college as how well you did (your GPA (grade pooint average)) and your test scores. If you are trying to get into a really prestigious college it would matter more.

18 * 35 = 630 total students 630 / 30 = 21 total classes An additional 3 classes.

You reduce each class by 5 (existing - new), and you have 18 classes (given).Multiplying, you have 90 extra students. To put them in classes of 30, divide.90 / 30 = 3 new classes.Three more classes because 18*35 = 630 and 630/30 = 21

You can take the ACT regardless of which classes you take. You can even take it before entering high school.
It always depends on the school. Some schools give you a schedule with classes in a random order. Some schools have predetermined classes. Most have schedules though. Source: I have been through middle school before.
