It doesn't really matter what classes you take in high school or even in college. The grades you get are more important.
Algebra, a language like Spanish or French, science
From the French classes I took back in High School... It is : Aujourd'hui ce n'est pas mon anniversaire
It would be good to know Spanish and French or Italian and French That way you can teach more classes and get a better chance at a job.
As much math as possible such as Algebra, Geometry and Trigonometry. Then drafting is important along with computer classes. Biology is also an important class.
So when you go into high school you know what your going to do and then you can start taking some classes for it. Then if you get all of those classes done you could start on some of the college classes for whatever you want to do.
If you have a cooking ability, and want to learn to prepare a good authentic french food, than you can go to some good french cooking classes or to a cookery school.
Take any classes that count towards your high school credits so when your in high school you will have extra room for electives that can help you learn more about the field of criminology.
"You prefer classes in French!" in English is Tu préfères les cours en français! in French.
they are almost exactly alike, i went to a french immersion school until grade 8 and am now still taking french immersion in high school, my classes are split up half in English and half in french, but are the same subjects. We have all the same pros and cons (good teachers, bad teachers, tests etc.) but since the language comes naturally by now there is practically no difference in my classes.
