<p>I know this is a silly question, but I'm an International applicant and don't know what those are, as far as I could understand they are optional courses you take in High School, but that's all I know, we don't have such things in my country so if you could explain it better I would really appreciate! As there are no such things in my country, would the lack of High School Courses affect my application?</p>
<p>High School Courses is simply another word for classes, so if you graduated high school I would say that you wouldn’t be lacking any classes! :)</p>
<p>Thanks! But they are not optional then? All classes you attended in High School are called Courses?</p>
<p>Well, some are not required for graduation…at my high school I had to take every class in order to graduate with enough credits…</p>
<p>Depends on the school I suppose.</p>
<p>So in an application which asks what High School courses I took, I just put all the classes I attended?</p>
<p>yes, indeed</p>
<p>OK, thanks!</p>
