Current Year Courses' Credit for A-level students

<p>I have done GCSE A-level, which is somewhat different from the American high school system.</p>

<p>In the Common App, I need to declare my 'Current Year Courses' with their respective 'Credit Value'. And it is mandatory to fill out this information.</p>

<p>The problem is that A-level doesn't really have any credit hours, semesters etc.
I emailed Common App about it, and they weren't of much help either. Anyone on the same boat?? Care to suggest what I should do?</p>

<p>Thanks!</p>
