Well sometimes it is really hard, but sometimes it is not hard. It is with the questions if I got it right or not ^^
No, you weren't, because both the American and European schools would force you to move to another higher grade and / or school to do so. I personally was doing college math courses my freshmen year and earning AP credit, and have been in excelled education my entire life, and have an Associates Degree at 18, and work as an Interior Design Engineer of private jets for a company based in Colorado making more than enough money to support myself and my girlfriend, are you on the same track?
