High School Block Schedule - how to enter in Apply Texas app for UT Austin

My son’s HS uses a block schedule. In the Apply Texas app for UT Austin, you are required to enter your senior year schedule into the application, but they only have options for semesters and trimesters. As an example, my son has a 2 term ecomomics class that at many schools would be a full-year course but at our school you only take 4 classes each term so that class is taken in two terms (for him terms 3 and 4 so “second semester”.). If we only enter second semester it will look like he is only getting half the course credit he is. How did others enter block schedule courses into this application?? Thanks!

We have block schedule as well, have Econ in one semester (fall) and AP Government in the second semester (spring, right before AP exams). We entered Econ for one and Gov for the second. Texas universities are familiar with this so don’t worry.
