Experience learning abroad will depend highly on the school you choose to study in. What might work perfectly for another person may not work out as well for you, especially if you want to maximize your learning experiences?
It is always best to enlist the help of a dedicated travel company specializing in these experiences and work closely with them. You can also join the summer abroad courses for high school students to learn about the world and how to live in it.
One of the most important things you need to do is to find out what exactly you want to achieve from learning abroad. Some foreign schools specialize in a very specific field, like technology or agriculture, and maybe you want to bring that knowledge home with you.
Other schools have higher standards of learning that will make you more competitive in the job market. Still, other schools will help you sharpen your knowledge of the local language and norms. Define what you want and you'll know what kind of school will suit you best.
Now that you have a fair idea of what you want from an international school, the next thing you need to do is find out what international schools around the world have to offer. Examine the curriculum and see what kinds of lessons are planned out for your course. Don't just look at the names of these lessons but at the planned content that you will go through each semester.
