Question about the 'current year courses' section in the common app

<p>In my school the academic year is divided into 4 marking periods and the first two are called first semester and the last two are called second semester. The common app asks for the third trimester courses too...so what do I put down for that? Just leave it blank? And also, I have the same courses all the four marking periods, do I mention the same courses in both 'First semester' and 'Second semester' sections?
Thanks in advance guys!</p>
