+            The courses displayed are from the current year,
+            but since they are unlikely to change,
+            they can provide a good view for the courses next year.
+            However, this also means that the new courses
+            and courses that didn't open this year are not going to be displayed here.
+            For 2020, the new courses are Financial Algebra and Acc Psychology.
+            Also, by default, only the courses that current {{nextGrade.toLowerCase()}}s take are displayed,
+            and you can enable "show all courses" in settings if you want to see all courses.
