Secondary School
The name of the exam taken by French students after high school is called the Baccalauréat.
Getting a high school diploma could be a short term goal or a long term goal depending upon where you are in the process. If you have one more month of high school to complete, that is relatively short term. If you are just entering high school and expect to be there for four years, that is long term.
